INTRODUCTION
INESC-ID was created in 2000, as a result of the reorganization of the R&D activities of INESC
in Lisbon, and was awarded the status of Associate Laboratory (Laboratório Associado) in December
2004. The new institution was able to reach a compromise between the conflicting objectives of high
impact, long term research and more immediate, but equally important, technology transfer projects.
These two types of activities are crucial for an institution like INESC-ID that aims at creating value for
the country by developing new technologies.
INESC-ID now stands and is viewed as one of the most dynamic research institutes in Portugal in the areas of electronics, information systems, and telecommunications. In close cooperation with its partners,
INESC-ID has emerged as an institution of reference, intensely involved in a number of high visibility
projects that define the state of the art in these areas, both at national and international levels.
This report summarizes the main technical activities developed in 2008. In this year, INESC-ID continued to increase the quality and quantity of its research, while also paying renewed attention to technology transfer and creation of new ways to generate value.
This strategy for innovation continued to obtain visible results, as 2008 saw a significant increase in the
number of indicators that are very important. In particular, INESC-ID was successful in obtaining a large
number of FP7 contracts, being the most sucessful institution, for its size, in the ICT area. INESC-ID
has also continued to improve a number of other scientific indicators, such as publications and finished
dissertations.
This report presents, in a structured way, a brief description of the institution and an overview of the
most important results of the activities developed, together with some key management initiatives. A
listing of the most significant research projects undertaken in 2008 is included, in order to provide a
picture, although incomplete, of the main competences of INESC-ID.
A more detailed list of activities, organized by research unit, is also provided, and is complemented by a
full list of projects, publications and dissertations, included as annexes to the main document.

3.2 Special events and Opportunities
During 2008 INESC-ID continued to improve the quality of its research, by developing initiatives
that aim at fostering excellence in research.
3.2.1
Program CMU-Portugal
INESC-ID participates in the joint PhD Program Carnegie Mellon University-Portugal in the area
of Language and Information Technologies. This PhD program is part of the activities of the
recently created Information and Communication Technologies Institute (ICTI), resulting from
the Portugal-CMU Partnership.
The Language Technologies Institute (LTI) of the School of Computer Science at Carnegie
Mellon University (CMU) offers a dual degree Ph.D. Program in Language and Information
Technologies in cooperation with Portuguese Universities. The LTI, formed 20 years ago, is
a world leader in the areas of speech processing, language processing, information retrieval,
machine translation, machine learning, and bio-informatics. The breadth of expertise at LTI
enables new research in combinations of the core subjects, for example, speech-to-speech
translation, spoken dialog systems, language-based tutoring systems, and question/answering
systems.

§ Futurália, an event dedicated to education, training and employment. INESCID was represented in this high impact
event that occurred in December 2008,
with the research project iCat.
Besides the exhibitions, INESC-ID also
promoted and stimulated external visits,
mostly from other institutions and groups of external researchers or students from abroad.
Some examples are the visit of researchers from the Centre National de Recherche Scientifique
(CNRS), in March 2008, or the visit of Bell Labs in June 2008.
3.5 Cooperation and Mobility
INESC-ID promotes cooperation with other institutes and universities, and also with foreign
students. In 2008 took place several activities in cooperation with Euroyouth, which is a specialist training agency that promotes consultancy, administration, technical assistance and the
evaluation of professional training programs through fellowships.
Three short-term internships were developed within the direct supervision of INESC-ID researchers for young foreign students. These interships were a good example of high success
cooperation with Euroyouth.
Among the referred cooperation there were also organized some external visits to INESC-ID
research groups and activities. Greece and Turkey students, teachers and researchers visited
institution campues at Alameda and Taguspark, learning methods and sharing research and
academic experiences.

HIGHLIGHTS
4.1 IDeA
The project IDEA aims at the development of an
Autonomous Integrated System for the Automation of Anesthesia. This will provide a computational platform for clinical testing, both in animal
and human patients, that will form a significant
step towards reliable automation of anaesthesia,
both from the technological and scientific standpoints.
The main expected scientific contributions derive from the development of an integrated unit for
automatic anesthesia incorporating novel nonlinear and adaptive control reliable algorithms suitable for clinical environment.
vided by the automatic system, thereby improving the quality of anesthesia while keeping the
cost low.
The objective of this project is the development
of an autonomous integrated system for the automation of anaesthesia that incorporates advanced
control algorithms able to tackle the specific challenges of anesthesia. The system consists of a
multiprocessor unit that can be connected to
standard anesthesia sensors and actuators (perfusion syringes) and comprises two blocks.
Due to the ethical restrictions inherent to the experimentation on human patients, the test of the
final system will be mainly performed on animals
subject to anesthesia, although testing on human
patients will also be considered.
Automatic Control of Anaesthesia. In the last 10
years major efforts have been made in the development of new tools to monitor the brain activity
for evaluating the depth of anesthesia. The introduction of the Bispectral index from the electroencephalogram (BIS) or the entropy measure (EM)
for measuring the degree of unconsciousness are
examples of such improvements. These parameters complement the use of autonomic responses
which used alone do not adequately reflect the
level of consciousness and may lead to decisions
that increase the risk of anesthesia. The existence
of adequate monitors (sensors) like BIS and EM
and actuators allows the automation of anesthesia, motivated by the following issues:
• The anesthetist is relieved from repetitive tasks
and has more capacity to concentrate on patient supervision and on the decisions requiring
expert reasoning capabilities;
• Automation follows more systematic procedures, ensuring a tighter tracking of the target
values of the physiological variables to regulate, together with a reduction of the quantity of
drugs administered;
• In animal surgery, where for economic reasons
the surgeon many times has to play the double
role of anesthetist, an important aid will be pro-
Sensor and Control Technologies. One of the
blocks performs the functions associated to control and comprises control algorithms embedded
in a Digital Signal Processor that decides the dose
of drugs to administer such that the physiological
variables of the patient to control are close to the
desired target values. The variables to control are
21
the neuromuscular blockade (NB) and the depth
of anaesthesia (DoA) levels. Emphasis will be
placed on using the entropy measure of the EEG
to evaluate the DoA and insert it a feedback loop.
The other major block consists of a supervisor,
performing the functions of a Fault Detection
Monitor (FDM). This block verifies the correctness
of the actions undertaken by the controller block,
while being able to include the adequate high level of information on the patient’s state to the practitioner provided by software developed in other
projects. In particular, the FDM will detect malfunctions of sensors and actuators (e. g. blocking,
occurrence of outliers or unexpected behaviour),
oscillatory and other poor performance behaviour
of the feedback loop.
Multidisciplinary Team. In order to achieve the
objectives, a multidisciplinary working team has
been organized comprising experts from Control and Automation (INESC-ID, FCUP), Human
Anesthesia (HGSA), Animal Anesthesia (UTAD),
Mathematical Modeling of Anesthesia (FCUP) and
Computer Architectures and Electronic Systems
(INESC-ID). Most of the members from these
teams have a significant past experience of collaborative research on Monitoring and Control for
Anesthesia.
4.2 VIDI-Video
Video is vital to society and economy. It plays a
key role in the information distribution and access
and it will soon be the natural form of communication for the Internet and mobile phones. Current search engines, however, all rely on keywordbased access leaving semantic access to the
data to research.
The VIDI-Video project aims to integrate state of
the art components from machine learning, audio
detection, video processing, interaction and visualization into a fully implemented audio-visual
search engine.
The project will substantially enhance access to
video, by developing a semantic search engine.
The project will boost the performance of video
search by developing a thesaurus for automatically detecting instances of semantic concepts in
the audio-visual content.
Main objectives of the project are:
22
• To build a large scale thesaurus well-spread
over the semantic clues;
• To design, adapt and evaluate methods to learn
large thesauri of detectors;
• To define and evaluate powerful sets of visual,
audio, and cross-modal features;
• To deliver interaction with the user;
• To evaluate the approach in video news, documentaries and video surveillance.
The following technologies are investigated in this
project:
• Video segmentation, shot representation, audio
segmentation, joint audio-video segmentation;
• Audio event detection, speech recognition;
• Visual analysis: types of motion, actions and
behaviour analysis, motion events recognition,
Object recognition;
• Machine learning methods: learning optimal
linear projections, fusion of multiple similarity
measures, kernel discriminant analysis using
spectral regressio, and inverse random under
sampling.
Highlights. This three-year project has just undergone the review of the second year. The highlights
for the second year were:
• Project team published thirteen papers in prestigious journals (e.g. IEEE Transactions on Pattern Analysis and Machine Intelligence, IEEE
Trans. Image Processing, IEEE Multimedia in
2008) and about 35 conference publications;
• The visual categorization system developed within the VidiVideo project (WP4-WP5)
achieved the highest performance in the PASCAL VOC 2008 object recognition task and the
TRECVID 2008 concept detection task;
• A novel video segmentation method for gradual
transition detection was developed and the
method significantly improved performance
over previous state of the art approaches;
• Audio speech versus non-speech classification
module has been retrained on augmented data
set, false detection error has been reduced significantly. The gender audio recognition system
has been improved with the addition of a new
class “child”;
• New baseline detectors for a wide range of audio
semantic concepts (nearly 50), including promising hierarchical clustering approaches, were
added. There are continuous improvements of
baseline European Portuguese speech recognition system. The significant improvement of
speech recognition system for the English language (the target language of the project) has
been achieved. The national TV station in Portugal (RTP) started using the Portuguese speech
recognition system for on-line subtitling of the
major news shows;
• A novel method for periodic motion detection
was developed. The visual categorization system was speeded up by employing generalpurpose GPU computing on consumer graphics cards;
• Four new machine learning methods directly
applicable to the automatic annotation problem
were developed;
Prototype. The first version of the prototype of the
VidiVideo final system was created for linux platforms. The first prototype was extensively tested
on 25 training videos, 27 testing videos. The second prototype with more efficient new modules incorporated was created. The thesaurus of detectors reached around 680 concepts (both for video
and audio), reaching two thirds of the number
expected by the end of the project. Three different query tools are currently under development:
the surveillance domain tool, the documentaries
domain tool, the news domain tool. Partner Netherlands B&G prepared both audio data and video
data to other partners. B&G also participated in
the design of the video annotation tool. The query
logs from B&G archives have been analyzed and
the most relevant concepts have been derived.
4.3 STOP-Fire
The main goal of this project is the development
of a computational intelligence based distributed
system prototype that can produce contingency
plans to control and combat forest fires based on
available resources (water, equipment, aerial and
terrestrial vehicles, firemen, etc.) and geographical, topological and meteorological restrictions.
Control forest fires. Nowadays, the decision
making process of fire fighting is centralized at the
National Service for Fire and Civil Protection. Location and characteristics of all available equipment
23
and human resources is supposedly well-known
in real-time. Also, all geographical, morphological
and meteorological needed information is available. However, it is a fact that the decision making
process and the real time management of such
a high, scattered and diverse number of factors
and variables, demands skills that are very often,
above human real time capabilities. By using intelligent computing techniques (automatic learning,
fuzzy systems, neuronal networks, evolutionary
systems and genetic algorithms, etc.), it is possible to integrate all available technological resources and develop a system that is able to help
fire combat and therefore mitigate the effects of
the calamity the forest fires have become.
Prototype. The prototype will be composed of
several modules: an intelligent graphical forest
fire propagation simulator; an expanded fuzzy
GIS (Geographic Information System) associated
to a Data Mining system that extracts geographical and topologic relevant data; an Intelligent Data
Mining system to extract relevant available forest
fire combat resource data; an Expert system that
provides contingency plans based on meteorological data, real time constraints and information
provided by the previous modules. All modules
are components of a web based distributed system that should provide good performance and
remote accessibility.
The project is currently being developed at the
Spoken Language Systems laboratory, L2F, at INESC-ID. Some cooperation contacts have been
established with the National Service for Fire and
Civil Protection. Computational Intelligence techniques (automatic learning, fuzzy systems, cellular automata, evolutionary systems and genetic
algorithms, etc.) are used both to predict forest
fire evolution and to elaborate contingency plans.
The use of these techniques allows coping with
the uncertainty, lack of complete information and
qualitative properties associated with forest fire
combat aid.
Through the use of a distributed wireless environment, local information is used to better predict
forest fire evolution and to disseminate information on a more efficient way that will improve personal safety in fire combat.
24
Currently there is a prototype of a distributed system consisting on:
• An application running on PDA/smart phone that
can be used on the field during the fire combat,
where firemen can receive real time information
regarding the fire (maps containing GIS info regarding their position; the present burning area;
a prediction of the evolution of the fire including possible danger zones; etc.), and where real
time local data can be collected, introduced
and sent to the centralized server(position, local
weather conditions like humidity or local wind
directions, real state of fire in visible locations,
real time position of fire fighting teams, etc.);
• A server where the distributed information is
collected and added to a GIS database containing the relevant information to the fire combat;
• There is also an application being developed
that models and simulates forest fire propagation using Dynamic Cognitive Map Cellular
Automata, where Rule Based Fuzzy Cognitive Maps are used to represent the evolution
of burning areas in Voronoi region based cells.
This application will be integrated on the server
and will be used as an essential tool in forest fire
combat aid;
• On project completion it is expected to have a
complete Intelligent Distributed System for Optimization of Forest Fire Combat Aid.
The project started in December of 2008, and is
still in full development.
4.4 CleanDrive
The CLEANDRIVE Project has the objective of
developing an innovative and educational driving
simulator that integrates the dynamic driving experience with real-time calculations for fuel consumption and pollutant emissions.
Pedagogical Tols. While focusing on promoting a
safe and environmental friendly driving behaviour
the simulator also allows the user to make contact
with new technologies such as alternative fuels
(biodiesel, ethanol, etc). In opposition to common
simulation games, CleanDrive adopts pedagogical
tools regarding the rules and the scoring method.
To achieve this purpose, CleanDrive estimates in
real time the pollutant emissions and the fuel consumption, depending on the driver behaviour; at
the same time, it accounts the driver’s traffic offences and it incorrect behaviour.
Realistic Interface. In order to guarantee a realistic visual interface it was developed real-time
rendering software tools and three-dimensional
physical models. In addiction a physical support
was built which includes not only the computer
equipment but also the sound and video systems
and a group of commands (steering wheel and the
pedals) which promotes a more natural and real
driving.
As an innovative driving simulator, CleanDrive has
social and educational objectives such as:
• Educational driving simulator that promotes
safe and environmental friendly behavior;
• Integration of eco-game philosophy with realtime rendering software tools and 3D physical
models;
• Real time calculation of the vehicle dynamics,
fuel consumption and pollutant emissions;
• Promotion of alternative fuels and new propulsion systems technologies.
The main features of the simulator are:
• Possibility to create urban and non-urban environments;
• Vehicles with realistic physics behavior;
• Fuel emission calculus in real time;
• Sensibilization about the importance of ecological driving;
• Possibility to drive in a 3D environment;
• “Real-life” Traffic Rules;
• Realistic Artificial Inteligence controls the behavior of other cars;
• Real time display of ‘Instant pollution’;
• At the end of the simulation is displayed the ‘total accumulated pollution’.

4.5 ICONS
The goal of this project is to design and prototype
a microelectrode stimulation system for cortical
neuroprosthesis. It includes the design and prototype of an integrated microelectrode stimulator
for an intracortical neuroprosthesis.
Microelectrode stimulation system. The implantable microelectrode stimulator uses flip-chip
technology to be fully implantable without wiring,
reducing the risk of infection and increasing robustness. It is small enough to be undetectable
and has low power consumption obtained directly from the carrier, through an RF low-coupling
transformer, discarding the need for batteries. The
system architecture and circuit techniques which
overcome some of the application issues identified in previous solutions and prototypes.
Biomedical applications have seen an intense research effort in the last few years. Due to its huge
complexity it is a multidisciplinary area where microelectronics plays an important role in the feasibility of most systems. Typical implantable stimulators for biomedical applications are in the area
of muscular or nerve stimulation, for heart, limbs
or hearing diseases. Some of these applications,
such as pacemakers, require very low power systems; it avoids the replacement of batteries, but its
action requires also almost no signal processing.
Biomedical implementations in the field of visual
rehabilitation are integrated in its early stages.
Besides the mechanical and optic mechanisms
associated with vision which are already fully
understood and can be corrected by surgery or
external lenses, other mechanisms like the image
processing that takes place from the retina down
to the visual cortex is still not well known. Recently, research results have been presented on
the stimulation of the visual cortex to improve the
quality of life of the blind or partially blind.
26
System architecture. In this project we address
an integrated microelectrode stimulator system
for a wireless intracortical neuroprosthesis, with
high bit rate (video). The system architecture is
divided in two parts: a primary system placed
outside the human body, where all the processing takes place, and a secondary system placed
inside the human head, to estimulate the visual
cortex through the electrode array.
Traditional solutions to interface the implant with
data and power use a wired link; however, it requires a large number of wires and an electrical
connector implanted in the body which, apart
from the discomfort, poses a serious risk of infection. With RF coupling, data and power can be
obtained directly from an RF low-coupling transformer discarding the need for batteries or wiring.
On the other hand, simultaneous bidirectional
communication allows driving, and also acquiring,
signals to, and from, the microelectrodes (it can
be neuronal signals or signals sensing the state of
the system). These characteristics will also open
the possibility of applying the system to other applications that require bidirectional high rate communication.
Circuit Design. This project intends to address
the design of the circuit as four different blocks:
• The block that interfaces with the transformer
secondary which is composed by: the power
supply circuit (power module), the clock recovery circuit, and both the data modulator and
demodulator (RF processing modules);
• The data processing control block which is
composed by the input and output data processing blocks (digital modules);
• The electrode stimulator block which has a digital-to-analog converter (DAC) as a signal conditioning unit, a electrode buffer and a analog-todigital converter (ADC) for electrode monitoring
(analog modules)
• The microelectrode arrays to be designed on
house and processed over a CMOS integrated
circuit using flip-chip technology in order to be
fully implantable without external wiring, reducing the risk of infection and increasing robustness.
The prototype will be tested using the retina model
and primary system (discrete solution) developed
by this project team in a former European project
(Cortivis). The INESC-MN institute will develop a
new version of the neural microelectrode stimulator with both capacities of exciting and sensing,
by using its own technology to develop magnetic
junction tunnel sensors. Theses microelectrodes
can take advantage of the architecture developed
in this project for bidirectional communication.
In this project we intend to implement a complete
secondary system as System on Chip (SOC) solution integrated with the microelectrode array.

DETAILED
ACTIVITIES
REPORT
5.1 Spoken Language Systems
Spoken language processing is a strongly interdisciplinary area, requiring expertise in very distinct topics, such as signal processing, machine
learning, artificial intelligence or linguistics. The
Spoken Language Systems Lab was created in
2001, although the earlier work dates from the
late eighties, to bring together researchers from
all these areas, with the mission of bridging the
gap between natural spoken language and the
underlying semantic information, with a special
emphasis on Portuguese. This joint expertise allows research efforts in collaborative areas such
as semantic multimedia processing, spoken/multimodal dialog systems, speech-to-speech translation, computer-aided language learning, and einclusion.
Dialog platforms also combine multiple core technologies such as speech recognition, speech
synthesis, animated face processing, text processing, and dialog management. Our goal has
been to develop a generic platform that can be
accessed via microphone, telephone, GSM, PDA
and web, thus requiring the creation of a domainindependent level to the dialog manager.
Semantic processing of multimedia documents
entails a complex pipeline of blocks in which the
group invests strong research efforts: audio segmentation, including partioning into blocks from
the same speaker, speech recognition, enrichment of the automatically produced transcription
with punctuation and capitalization, dealing with
the disfluencies that characterize spontaneous
speech, segmentation into stories, topic classification, language identification, and summarization.
target language for CALL is a very ambitious goal.
The complexity of S2SMT systems is well justified by the integration of several modules: speech
recognition, machine translation and speech synthesis.
The next two research directions are much more
recent in our group: speech-to-speech machine
translation (S2SMT) and computer aided language learning (CALL). Both are two strongly multilingual, multidisciplinary areas with an enormous
application potential. Setting Portuguese as the
source or the target language for S2SMT and the
In CALL, virtually all text processing technologies
can be integrated, as well as several speech processing ones (phone recognition, pitch analysis
and speech-to-text alignment).
29
The last application area which has been the
objective of our continued efforts is e-inclusion,
namely the development of alternative and augmentative communication tools for people with
special needs.
In December 2008, the group included 9 researchers with a PhD degree (7 University professors,
and 2 post-docs from Spain and France), who supervise many PhD and MSc students.
5.1.1
Activities
The group’s activities during 2008 have been carried out in the scope of a significant number of
national and international projects.
30
National Research Projects
The highlight of national projects has been the
group’s very active participation in the recently
finished Tecnovoz project, aimed at deploying
speech technologies to many different areas of
application: automatic subtitling, stock exchange,
banking, insurance, transportation, and medical
applications, telephone monitoring, and e-inclusion applications. The total budget of this 2-year
project (2006-2008) was 6.36 M€ with 47% for research institutes, and the remaining for the 9 participating companies. One of the most important
activities of our group in this area was the automatic broadcast news captioning system which
is currently deployed at the Portuguese national
TV station (since March 2008). The automatically
produced transcriptions are enriched with punctuation and capitalization, and an off-line version
filters the contents of multimedia documents by
using topic segmentation and indexation, summarization and automatic language identification.
Another very important activity within the Tecnovoz project is the development of spoken/multimodal dialog systems for a variety of scenarios.
One of the most flexible scenarios is provided by
our IVR (Interactive Voice Response) platform,
which integrates our recognition and synthesis
engines with a dialog management module (DIGA)
that supports the Voice XML norm. The IVVR (Interactive Voice and Video Response) platform enhances the user interface with an animated talking
face (FACE). A significant amount of the Tecnovoz
resources was also devoted to the development
of the recognition and synthesis engines that had
been the target of the efforts of our researchers
since the early nineties (AUDIMUS and DIXI+, respectively).
In terms of speech-to-speech translation, the
work started in the framework of the past WFST
project and which had culminated in the recent
development of speech-to-text broadcast news
translation system for Portuguese to English and
Spanish, launched the basis for a successful proposal in cooperation with CMU.
Our preliminary work on computer aided language
learning also constituted an excellent basis for yet
another successful proposal in cooperation with
CMU on this topic.
Significant progress has been achieved in national project POSTPORT targeted at porting the
speech technologies the group has developed for
European Portuguese to other varieties, namely
those spoken in South-American and African
countries, with Portuguese as official language.
In this framework, we have developed automatic
identification systems for 3 main varieties: European, Brazilian and African, we have developed
grapheme-to-phone conversion systems for Brazilian, and ported our broadcast news recognition
system to both varieties.
International Research Projects
In terms of international projects, the main project
of the group in the area of semantic indexing is
VIDI-Video, a European project whose aim is to
implement a search engine with a 1000-element
thesaurus, by detecting instances of audio, visual
or mixed-media content. Significant progress has
been achieved in this project, namely in terms
of detecting around 50 different audio events. In
terms of audio segmentation, our gender detection module, which was targeted at distinguishing male and female speakers only, has been
extended to encompass age distinctions as well.
This part of the work targeted at child voice identification has been carried out in cooperation with
the I-DASH European project, whose goal is the
identification of child abuse videos in the internet. In terms of speech recognition, we continued
the improvement of the English, Portuguese and
Spanish recognizers. Our participation in an international automatic language identification evaluation campaign was also very successful.
The cooperation with the GAIPS (Intelligent
Agents and Synthetic Character) group of
INESC-ID, which started in the framework of the
national project PAPOUS, “the story teller”, has
been crucial for the development of multimedia
applications. These activities are now carried out
in the framework of European projects E-Circus
(Education through Characters with emotional
Intelligence and Role-playing Capabilities that
Understand Social interaction) and COST 2102
(Cross-Modal Analysis of Verbal and Non-verbal
Communication). The LIREC project (LIving with
Robots and InteractivE Companions) is also developed in the framework of this very successful
cooperation. It aims to establish a multi-faceted
theory of artificial long-term companions (including memory, emotions, cognition, communication,
learning, etc.), embody this theory in robust and
innovative technology and experimentally verify
both the theory and technology in real social environments.
Other European joint efforts in which the group
also participates are COST 2103 (Advanced Voice
Function Assessment) and ECESS (European
Center of Excellence on Speech Synthesis).
5.1.2
Events
The group was represented in Technical Program
Committees of major Conferences and Workshops
in the areas of Speech and Language Processing
(COLING, ICASSP, ICME, INTERSPEECH, LREC,
PROPOR, ISCA ITRWon “Speech Analysis and
Processing for Knowledge Discovery”). Also worthy of note is the keynote invitation for IEEE SLT.
The editorial activities of the group during the
past year assumed a particular relevance given
the participation in the Editorial Board of Signal
Processing Magazine, and Guest Editor of Special Issue on Iberian Languages (Speech Communication, Elsevier).
The group was representated in the major international organizations in the spoken language
porocessing community: IEEE SLTC (Speech
and Language Technical Committee), IEEE SPS
BoG (Signal Proc. Society Board of Governors),
and the Presidency of ISCA (International Speech
Communication Association).
5.1.3
Services
The Tecnovoz project laid the groundwork for the
recent creation of a spin-off company (Voice Interaction), with which we plan to continue our technology transfer efforts.
31
5.2 Information and Decision
Support Systems
Our society is heavily dependent on information
systems which support the whole structure of the
economic and social framework. Therefore, the
domain of the processes, techniques and technology for the analysis, design, development and
integration of information systems represents
actual and fundamental areas of knowledge, required to assure aligned, safe, reliable and trustworthy solutions.
On the other hand, the generalized use of devices
and techniques for data acquisition, transport and
storage raises endless new social problems and
challenges, especially to privacy, requiring techniques for data security and controlled use of sophisticated analysis methods for the detection of
fraud, abnormalities and tendencies.
INESC-ID gathers a body of competences in these
areas that renders it a national and international
reference. In particular, it incorporates researchers
who are internationally recognized in the areas of:
• Information systems analysis, design, development, integration and management;
• Architectures and technology for the Internet;
• Methods for data analysis and data mining;
• Algorithms for efficient manipulation of large
volumes of data;
• Security in distributed systems (e.g. for grids);

• Algorithms and tools for constraint solving;
• Computational intelligence;
• Systems and algorithms for biological data
analysis;
• Geographic information systems;
• Digital libraries;
• Information system’s interoperability and metadata;
• Digital preservation.
32
The integration of these competences leads INESC-ID to position itself clearly as a reference, on
a national level, for providing specialized services
to public and private entities requiring specialists
with unquestionable reputation within their areas
of work.
5.2.1
Activities
Within this thematic area, the activities promoted
to maintain INESC-ID as an excellence centre at
international level were the development of:

systems, ontology engineering;
• Development of state-of-the-art research in algorithms for Constraint Solving;
• Development of information systems for biological data analysis, including algorithms and
methods to process gene sequences and gene
expression data.
National projects
SHIPS
The haplotype inference problem is related with
identifying genetic variations among different
people. These variants explain much of the genetic diversity in our species, and comprehensive
search for genetic influences on disease involves
examining all genetic differences in a large number of affected individuals. This allows the systematic test of common genetic variants for their
role in disease.
The focus of the SHIPS project is to develop new
Boolean algorithms and models for solving the
problem of haplotype inference by pure parsimony.
Experimental results show that this problem is
better solved using effective Boolean constraint
satisfaction methods.
BSOLO
The representation of computational problems
with constraints involving Boolean variables has
widespread use in Electronic Design Automation,
Artificial Intelligence, Operations Research, and
Computational Biology, among many other areas
of science and technology.
The aim of the BSOLO project is at developing
new algorithms and strategies for solving problems with Boolean domains. Moreover, new problems in several areas will be tackled and solved
using Boolean models, namely in bioinformatics,
model verification, among others.
OntoSeaWeb
Ontology Engineering for the Semantic Web, had
several lines of research which all aimed at developing methodologies and methods to ease
the process of building ontologies, allowing nonknowledge engineers to build them. In particular
it researched how to automatically build ontologies to be used and applied in the Semantic Web,
the first methodology for Ontology Risk Analysis
was devised and tested in several case studies,
the DILINGENT methodology was developed and
tested in real user environments. Moreover, ontology based annotation was pursued. As a result
a documents ontology was built in a semi-automatic way.
FolkPeers
Folksonomies in P2P systems, researches the
construction and use of social content management systems. Issues to be studied include tagging suggestion, context navigation to allow better use of these systems, relationship analysis
between users and their use habits.
CLAW
Cyclic Learning and Annotation of the Web, targets both ontology relation instantiation from the
analysis of textual sources using shallow methods
and the development of similarity measures for DL
ontologies. Texts from IMdB are being used.
IR-BASE
An Integrated Framework for the Research and
Teaching of Information Retrieval Technologies.
33
International projects
o Adequateness of the effort estimated by the
proposal to the allocated resources;
o Robustness of the system concerning physical and logical failures.
MANCOOSI
System upgrades may proceed on different paths
depending on the current state of a system and
the available software packages, and system administrators are faced with choices of upgrade
paths, and possibly with failing upgrades.
The Mancoosi project aims at developing tools for
the system administrator namely develop mechanisms that provide for rollbacks of failed upgrade
attempts and develop better algorithms and tools
to plan upgrade paths based on various information sources about software packages and on optimization criteria.

5.3 Interactive Virtual
Environments
Interactive virtual environments assume great
strategic importance, given the foreseen evolution
of interaction paradigms, either in supporting human-computer interaction or supporting remote
computer-mediated interaction amongst people
within Virtual Worlds. INESC-ID has a large number of researchers who develop their activity in a
set of disciplines highly relevant to interactive virtual environments.
Specifically two groups, VIMMI and GAIPS feature core competences in:
• Devising multimodal interaction models within
virtual environments by using interfaces based
on synergistic recognition of multiple interaction modalities;
• Architectures for cooperative virtual environments by using algorithms for gesture recognition and artificial intelligence techniques for
creating realistic synthetic characters;
• Affective computing applied to the generation
of believable synthetic characters and humancomputer interaction;
• Software architectures for virtual environments,
with emphasis on image synthesis algorithms,
intelligent agents programming and effectively
using component based design and development patterns.
For the reasons mentioned above, the institution
is regarded as an excellence centre in this area,
with internationally recognized competences and
the ability to provide a set of services of great relevance to our strategic focus areas.
35
5.3.1
Activities
National Research Projects
In terms of nationally funded projects, in 2008 we
successfully finished three FCT projects:
BIRD, where we were the prime contractors, we
advanced the state of the art in the emergent area
of Personal Information Management, by showing
how autobiographic information about the users
and the context in which they handle their documents can be used to retrieve that information at
a later time.
The DecorARproject, where we participated as
prime contractors as well, used Augmented Reality techniques and sketch-based interaction to
facilitate multimedia information retrieval, with
emphasis on the retrieval of 3D representations of
furniture to include in a tool of interior decoration.
In the context of third project CleanDrive, we developed an Environmental and Safe Driving Simu-
via: A theoretical framework for group attention;
A collection of attentive devices that can be integrated in CSCW systems and tools; Results from
laboratory experiments with attentive devices; A
group performance model based on attention; A
collection of best practices for designing attentive CSCW. During this year we participated in the
development a set of attentive devices, and its
application in a chat tool, to improve the communication person-person mediated by a computer.
We started, as prime contractors, another FCT
project called VIZIR. It aims at developing efficient parallel algorithms to make it possible to
interactively visualize and navigate within massive
data sets in commodity clusters for high resolution screen devices such as large tiled displays.
Interacting with these data sets remains a difficult
and challenging task in particular when real time
response is needed and crucial for the observation of natural phenomena. Indeed, rapid devel-
lation tool for Educational Purposes. In particular,
we developed a package which consists of simulation software and a physical support (computer,
pedals, steering wheel, seating, sound system)
enabling the players to use the simulator in a way
similar to a regular vehicle.
36
We also continued our work in FCT project ACSCW. Its main objective is to study how technology may positively influence group attention
in the collaborative context. This objective will be
accomplished by researching the following questions: How collaborating individuals divide their
attention between the group and the individual
tasks? How can technology positively influence
the attention to the group? Which computer devices improve group attention? What are the
guidelines to incorporate such devices in future
CSCW systems? What are the expected performance improvements? Answers to these questions will be supplied to the research community
opments in three-dimensional scanning technologies currently allow capturing very large models in
fine detail with geometric and textured data.
Another relevant activity was developing multimodal interfaces for helping citizens with special
needs in their everyday activities. This comes in
the wake of a four-year long activity with blind and
visually-impaired people for learning, guidance
and improving the use of everyday devices such
as mobile telephones. A prototype system has
been used by eight blind people over the course
of 14 weeks.
International Research Projects
In 2008, we continued our work in the European
Sixth Framework programme project E-CIRCUS
(Education through Characters with emotional-Intelligence and Role-playing Capabilities that Understand Social interaction). Within the E-CIRCUS
project, we are developing technology to support
social and emotional learning within personal and
social education. This is achieved through virtual
role-play with autonomous synthetic characters
that establish credible and empathic relations
with the learners through affective engagement.
We are doing this by taking modern theories of
interactive narrative and role-play from psychology and implementing them in affectively driven
autonomous graphically embodied agents – actors with attitude.
In the last year, as an evolution of our first demonstrator (FearNot!, which is focused on anti-bullying education), we concluded our second demonstrator, ORIENT. The ORIENT demonstrator is
in the area of refugee children in schools. In this
application, role-playing characters interact with
child users to create inter-cultural empathy, supported by a state-of-the-art interactive narrative
framework.
More information: http://www.e-circus.org
In 2008, we started our work in the European
seventh framework programme project LIREC
(LIving with Robots and Interactive Companion).
The LIREC project aims to create a new generation of interactive, emotionally intelligent, companion technology, that is capable of long-term
interaction with humans, in both a virtual world
(as synthetic characters), and in the real world (as
robots). To date, artificial companions have had
limited abilities to support long-term, meaningful
social interactions with users in real social settings. The project will also examine how we react
when a synthetic entity swaps from a robot body
into a virtual form.
Within the last year, we developed long-term scenarios and started prototyping and evaluating
user modeling techniques adapted to long-term
interactions.
More information: http://www.lirec.org
We started our work in the IP European project,
TARGET, in which we are studying how serious
games and immersive environments can be used
as the means for knowledge workers to gain new
competences, facilitating the acquisition of threshold concepts that improve their effectiveness and
quality when facing demanding situations in the
workplace. We will lead the development of a customizable framework where such games can be
developed, tailored to the needs of different entities and employees.
We continue our research under the scope of the
European project SATIN on the new generation
of multimodal and multisensory interfaces, supporting free-hand interaction with virtual shapes.
SATIN main goal is to develop a system for 3D
shape modification and exploration by means of
free hands using the metaphor of “tape sketching” and the metaphor of “bending along curvilinear trajectory” under the control of integrated and
fused visual, audio and haptic feedbacks. During
2008 we developed the second prototype of the
visualization system integrating the deformable
version of the haptic strip. It provides to the user
a mixed reality environment where virtual shapes
can be evaluated and edited physically. Our visualization system resulted on a new open source
framework named Open5 (Framework for Interactive Virtual Environments) developed for rapid
prototyping of virtual reality applications.
37
We are also involved in MAXIMUS, a project that
started in March 2008, and aims to develop the
first system to fully support high dynamic range
information throughout the pipeline. Starting with
high dynamic range material and light acquisition, providing a high dynamic range real-time
light simulation and rendering pipeline and finally
displaying maximum fidelity image quality with
color gamut enhanced stereoscopic high dynamic range projection technology to bring the total
dynamic range to over 5.000.000:1– a real breakthrough in display technology. Natural gadgetfree multi-modal interaction techniques will allow
multiple users to easily interact with virtual objects, virtual light sources and materials to compose and configure scenes and evaluate lighting
effects rendered in real-time. The system will be
evaluated in the professional markets of car styling, architecture and industrial design.
In the context of the Eurotooling 21 project, we
developed a tool to support mould makers in performing quotations of moulds. This tool includes
and improves sketch-based retrieval technology
developed in the past project SmartSketches.
We are also developing a CAD Conference tool,
to allow mould makers to discuss, annotate and
collaborate during the process of mould maintenance, setup or design.

5.3.3 Services
In 2008, we started our consulting activity for YDREAMS Informática S.A., in the context of “Programa Operacional Regional de Lisboa” project
Chameleon (Construction of Humane Autonomous Machines Embodied in Living Environments
of Nature). Within project Chameleon, we are providing consulting services in social cognition and
cognitive processes, namely affective computing
and believable interactions.
We’ve led and participated in two projects with direct impact to the society at large, as the creation
of a C.A.V.E. (Cave Automatic Virtual Environment) system for the Lousal Ciência Viva center,
and Eco-Driving, a simulator promoting ecological
driving practices to be used by Câmara Municipal
de Vila Franca de Xira.
Concerning the for the C.A.V.E. system installed
in Centro de Ciência Viva das Minas do Lousal,
we developed also a project, named “The Journey to the Center of the Earth”, which is a virtual simulation designed from the ground up to
run over CAVE immersive system. The applica-
tion was created to simulate a fiction journey to
a hollow center of the earth, inhabited by strange
creatures. The journey has three main sections (or
maps): an initial tunnel, a rollercoaster section on
mine carts and a simple cavern environment over
at the center of the earth.
5.4 Embedded Electronic
Systems
The main goals of this research unit are: to perform advanced research in fundamental areas
that support the design of Embedded Electronic
Systems; to train human resources at M.Sc. and
Ph.D. levels; to provide advanced courses and
technology transfer to industry and to support the
creation of start-up companies from our researchers and students.
The implementation of embedded systems (digital, analogue, or mixed signal) as components or
cores (embedded cores) of integrated systems
(SoC, Systems on a Chip) adds value, not only
to large companies, but also to SMEs operating
at national level, as long as specialized human
resources exist in sufficient number and quality.
Currently, in the SIP (Semiconductor Intellectual
The Embedded Electronic Systems research unit
is organized in four scientific areas: Electronics
and EDA, Signal Processing, Control and Computer Engineering having more than 33 Ph.D. researchers and 24 Ph.D. students.
Property) market, there are successful SMEs with
a business based on the design of IP (Intellectual
Property), which are marked under the form of either material or virtual cores (hard or soft cores).
Even large companies are already relying on outsourcing of project activities in this area which
require multi-disciplinary know-how ranging from
algorithms and architectures to telecommunications, image processing, biomedical applications,
modelling, monitoring, supervision and control of
industrial processes.
Information and Communications Technologies
(ICT) are a fundamental part of the new information and knowledge society. The electronics industry is one of the key driving forces supporting
the sustained growth of ICT potential in Europe.
Besides production manufacturing areas, there
is a vast set of manufacturing opportunities connected to the development of new products and
associated services.
These opportunities are highly dependent on research and human resources trained in highly specialized project methodologies and tools. Among
these systems, special emphasis goes to embedded electronic systems, programmable, not only
in terms of software, but also in hardware.
INESC-ID has available highly qualified human resources in the supporting technologies of digital
electronics, analogue electronics, microelectronics, radio frequency electronics, instrumentation
and test, adaptive control, predictive control, fault
tolerant control and reconfigurable systems, computer systems architecture, programmable electronic systems, scientific computing, electronic
design automation, and sensor networking. Its
researchers also master the design, manufacturing, test, and debug techniques, necessary for
39
new product development and follow-up of this
area of crucial industrial and social importance.
The use of these technologies in the areas of telecommunications, energy systems, industrial automation, automotive, and aero-spatial applications
and in the emerging areas of electro-medicine and
bio-engineering will require the collaboration of
institutions with deep knowledge of system conception and implementation with semiconductor
technologies.
INESC-ID possesses internationally recognized
key competences in this scientific area and has a
strong drive to provide services in this area, as a
result of its experience in European and national
projects.
• Processing architectures and embedded processors, for dedicated applications and for
general use;
• Hardware compiler techniques and custom reconfigurable computing architectures for embedded systems;
• Non-linear, adaptive, reconfigurable and hybrid methodologies for the development of algorithms and control applications, suitable to

the RF frontend and in the baseband processing algorithms and architectures;
• Integrated circuits design - power management,
analog and RF circuits, and digital circuits – for
low-power and low voltage.
5.4.1 Activities
40
During 2008 this line of action was restructured.
The number of research groups was reduced by
merging smaller groups and a common laboratory
was created where the most expensive equipment is shared by all the elements of this research
unit. As a result, the number of collaborative
projects and joint supervision of Ph.D. thesis increased, giving to this line of action the capability
to address larger multi-disciplinary projects. The
research subjects covered by this line of action
range from conception of circuits and systems
to physical implementation at different hierarchy
levels.
The main topics of research can be summarized
by:
• Algorithms for design automation with emphasis on (1) power estimation, optimization and
distribution, and (2) synthesis of digital processing systems using pseudo-Boolean models and
optimization tools;
• Algorithms, methodologies and tools for the design and test of highly integrated electronic circuits
and systems, digital, analog and mixed-mode;
This know-how leads to the realization of some
multi-disciplinary collaborative projects, with
stringent performance requirements, such as:
• Medical imaging hardware/software systems
using Positron Emission Tomography (PET)
technologies for mammography;

A start-up company, PETSys – Medical PET Imaging Systems, S.A., targeting the design, development, implementation and commercialization
of imaging systems for medical diagnosis and
research, was founded by the PET consortium
in 2008 with a strong participation of two groups
from this line of action.
This line of action organized in 2008 the following
events: Organization of the International Workshop on Power and Timing Modeling Optimization
and Simulation 2008, PATMOS 2008, September
10-12th , Lisbon, Portugal.
Within this line of action, consulting services on
the following areas were performed:
• Design and test of reconfigurable embedded
electronic systems and ASICs (Application
Specific Integrated Circuits), for wireless communications, medical diagnostics instrumentation, telemetry, advanced computing, and education; done in partnership with Tecmic, INOV,
Integration and Chipidea;
• Design and test of EDA (Electronic Design Automation) tools; there has been ongoing research
and testing of new algorithms and technology

5.5 Communication Networks
and Mobility
42
The concept of mobility is increasingly more important in the development of products and services for the information society. In effect, it is fundamental for the information to be available from
any location, at any time and using any type of
terminal. Integration of different networks (mobile,
fixed, local and wide area) is not only an emerging
reality but a real need felt by the general public.
the mobile and wireless network infrastructure.
We capitalize not only the knowledge acquired in
state-of-the-art scientific research, but also the
experience gained in the practical implementation
of the virtual campus concept, with the institute
currently integrated, in a transparent way, with
Instituto Superior Técnico’s fixed and mobile networks, sharing its resources and infrastructures.
Fixed and mobile communication networks and
the mobility they provide, have a strategic importance, given the fact that they represent an important infrastructure. Within this area we gather
the competences existing in the area of network
architectures (fixed and mobile) which enable the
integration of classic technologies, traditionally
separating networks into two different domains:
telecommunications and computer systems.
Given the recent developments, it is clearly crucial to integrate both domains, both at network
infrastructure level and at the level of services and
applications.
Research and development work performed in
the networking area, both in the context of national and international projects, and the context of
post-graduation theses, led to the development
of competences recognized through the awarding
of various prizes and the participation, as representatives of national operators, in several standardization bodies, namely ITU and ETSI, and research coordination in international projects and
bodies.
A special important area for the increasing mobility of citizens is related to ad-hoc networks, which,
due to the fact that they do not possess high requisites in terms of planning and installation, may
become extremely relevant in specific domains of
society, namely military and civilian protection.
The activities developed within the scope of Associate Laboratory were as follows:
• Development of state-of-the-art research in
fixed, mobile and ad-hoc communications networks technologies;
• Development and maintenance of communications networks demos for specific support
to applications with high quality of service requirements, such as the case of IP telephony,
applications to support collaborative work and
distance learning or video broadcasting on demand;
• Specification, implementation and test of the
physical and logical infrastructure of mobile
networks which enable the generalized access
of citizens to the information in various environ-
INESC-ID competences in this area cover different aspects which are key to the use of communications networks. Emphasis goes to the work developed at the levels of quality of service, network
management, security and robustness of wireless
networks, besides other types of challenges imposed by mobility. INESC-ID is particularly well
positioned to develop research in this field, both in
areas related to fixed network infrastructure, and
5.5.1 Activites
ments, such as Universities, schools, airports
and other public places;
• Specification, implementation and test of adhoc networks, which enable the existence of
communications infrastructures in situations,
or places, in which the installation of other network types is not viable;
• Development of actions that raise awareness
of the various aspects of communications networks which allow support to applications with
quality of service.
5.5.2 Services
In 2008, the communication networks and mobility research unit mainly developed their services
in two areas:
• Project and development of networking integrated solutions.
• Project and development of solutions for the
support of multimedia applications with quality
of service control in the network.

Title: POSTPORT - POrting Speech
Technologies to other varieties of PORTuguese
Funding institution: FCT
Coordinator from INESC-ID: Isabel Maria
Martins Trancoso
Short Summary: The goal of this project is
porting spoken language technologies originally
developed for European Portuguese to other varieties of Portuguese, namely those spoken in
South-American and African countries. The two
main technologies to be investigated are speech
synthesis and recognition. Instead of porting
complete systems, we shall concentrate on the
linguistically relevant modules. Prior to this main
work, the project will involve two tasks: corpora
collection and characterization of the main differences between the studied varieties. The last task
concerns the automatic identification of spoken
varieties of Portuguese, which will be used as a
pre-processing stage for switching among recognition systems developed for specific varieties.

Title: LIREC - LIving with Robots and
InteractivE Companions
Funding institution: European Commission
– FP7
Coordinator from INESC-ID: Luís Miguel Veiga
Vaz Caldas de Oliveira
Short Summary: LIREC aims to establish a
multi-faceted theory of artificial long-term companions (including memory, emotions, cognition, communication, learning, etc.), embody this
theory in robust and innovative technology and
experimentally verify both the theory and technology in real social environments. Whether as
robots, social toys or graphical and mobile synthetic characters, interactive and sociable technology is advancing rapidly. However, the social,
psychological and cognitive foundations and
consequences of such technological artefacts
entering our daily lives - at work, or in the home
- are less well understood. Successful technology can only be delivered on the basis of strong
scientific foundations, and with partners in psychology, ethology, human-computer interaction,
human-robot interaction, robotics and graphical
characters, LIREC will advance understanding
45
of the concepts of embodiment, autobiographic
memory and social interactions in the context of
companions where the ‘mind’ might migrate to
differently embodied ‘bodies’.
Title: TECNOVOZ - Tecnologias de
Reconhecimento e Síntese de Voz

contribute for the development of the next generation SAT and SAT extensions algorithms. Also,
the project will actively pursue the practical utilization of SAT and SAT extensions in the realworld.
Title: SHIPs - Sat-based Haplotype Inference
by Pure Parsimony
Funding institution: FCT
Coordinator from INESC-ID: Maria Inês
Camarate de Campos Lynce de Faria
Short Summary: One of the main topics of research in genomics is determining the relevance
of mutations, described in haplotype data, as
causes of some genetic diseases. The haplotype
inference problem consists in inferring haplotypes from genotypes. For solving this problem, different approaches can be followed. For
example, following the pure parsimony criterion
the main goal is to minimize the number of required haplotypes. The main goal of this project
is to develop efficient algorithms for solving the
haplotype inference problem, mainly based on a
parsimonious approach, and to apply these algorithms to real data, in order to identify genetic
deseases.
Title: MANCOOSI - Managing the Complexity
of the Open Source Infrastructure
Funding institution: European Commission
– FP7
Coordinator from INESC-ID: Maria Inês
Camarate de Campos Lynce de Faria
Short Summary: The main objective of the
Mancoosi project is to develop the scientific
knowledge and build the tools necessary to manage the complexity of the open source infrastructure. This infrastructure is one of the essential
building blocks of tomorrow’s software architectures: the success of LAMP (Linux, Apache,
MySQL, Php) inside as well as outside the data
centers is clear evidence of this. Yet, this infrastructure undergoes a fast-paced and distributed
evolution that is too often maintained in ad-hoc
ways using tools and processes that have clearly
attained their limits today. There is a need for
new and innovative technology, and this is what
Mancoosi will provide.
We explicitly target the difficult problems that
arise when one wants to efficiently and safely upgrade a set of software components in complex
software infrastructures, like those found in open
source software distributions, which are among
the most complex software systems known,
made of tens of thousands of components that
evolve over time without centralized design: this
is a challenging endeavor.
We have chosen the Free and Open Source infrastructure as our main target, as it provides
today a real-world example of what tomorrow’s
complex, quickly changing software systems
will look like: the applicability of these models
and algorithms goes far beyond Free and Open
Source software, and technologies developed in
Mancoosi will pave the way to the maintainability
of the software systems of the future, especially
for systems of systems, even when they are not
Free or Open Source.
Title: BSOLO - Satisfação e optimização com
restrições Booleanas
Funding institution: FCT
Coordinator from INESC-ID: Vasco Miguel
Gomes Nunes Manquinho
Short Summary: The development of a new
pseudo-Boolean core framework and the integration of the proposed techniques is fundamental, not only for supporting research work
in related topics (e.g. model counting), but also
to increase the competitiveness of the software
package already developed. Without it, the visibility of our research work will decrease, as
well as the excellent performance obtained in
the pseudo-Boolean solver evaluations (results
available at http://www.cril.univ-artois.fr/PB07/).
With a more competitive solver, the BSOLO project will also pursuit the objective of being able
to integrate the new solver into real-world applications, namely in international companies from
Operations Research (OR) to Electronic Design
Automation (EDA).
Title: DATA MINING

Short Summary: The objectives of this project are the development of new techniques and
models for accurate simulation of biochemical
networks. Coupled with higher abstraction models, these techniques can be used to study the
properties of the state spaces of complex biological systems, using model checking algorithms.
Finally, these techniques and models will be applied to actual biological systems, with emphasis
on the regulation mechanisms of the FLR1 stress
response network of Yeast.

Title: DYNAMO - Dynamical Modeling, Control
and Optimization of Metabolic Networks
Funding institution: FCT
Coordinator from INESC-ID: Susana de
Almeida Mendes Vinga Martins
Short Summary: The first objective of this project is to develop and validate mathematical models and computational tools for the analysis and
simulation of the dynamical behavior of complex
metabolic networks. The main goal is to produce
interpretable models that accurately describe the
metabolic system and have prediction and generalization capabilities. A second objective is to
create control and optimization strategies to alter the fluxes and concentrations of metabolites,
both transiently and at steady-state, by proposing the manipulation of enzymes gene expression. A third objective is the creation of an integrative bioinformatics infrastructure to store the
experimental data and to implement and deploy
the algorithms developed, thus fostering model
interchange between systems. A forth objective
is the acquisition of experimental in vivo metabolite concentration time series data, the creation
of mutant bacterial strains with desired metabolic
behavior and the experimental validation of the
models previously proposed.

Title: ARN - Algorithms for the identification of
genetic Regulatory Networks
Funding institution: FCT
Coordinator from INESC-ID: Ana Teresa Correia
de Freitas
Short Summary: The objectives of this project
are:
- The development of new methods and models
to search and extract evidence of regulatory
mechanisms in biological data and literature.
This includes the improvement of the models
used to represent complex regulatory signals
and small functional RNA motifs and the development of algorithms to explore the cooperative
characteristic of all these signals; the development of algorithms for the identification of local patterns in expression data; and the development of text-mining methods for extracting
gene regulations from BioLiterature and from
gene annotations.
- The design of new algorithms to derive effective models for gene regulatory networks. This
includes the development of methods to piece
together information from different sources.
The project will use the YEASTRACT platform
(www.yeastract.com) as a launching pad for a
much more ambitious system.
Title: ERA-PG - Genome-wide analysis of
short RNAs as modulators in dehydration
stress tolerance using tolerant and genetic
model systems
Funding institution: IBET
Coordinator from INESC-ID: Ana Teresa
Correia de Freitas
Short Summary: Drought stress is a common
adverse environmental condition that seriously
affects crop productivity worldwide. Due to the
complexity of drought as a stress signal and the
fact that drought stress is difficult to manipulate,
deciphering dehydration tolerance mechanisms
is a major challenge.
The objective of this project is to explore potential
roles of regulatory small 21-25nt RNAs (sRNAs) in
dehydration stress tolerance. We propose to construct libraries of sRNAs from the desiccation tolerant model plant Craterostigma plantagineum,
the dehydration tolerant legume Medicago truncatula and the genetic model plant Arabidopsis
thaliana at different stages of dehydration. We
aim to identify new families of sRNAs using genomics tools and test the expression profile of
selected sRNAs. Our results will have important
implications for gene regulation under dehydration stress and also contribute significantly to the
long-term goal of having a comprehensive profile
of sRNAs in plants.
Title: EUCALYPTUS - Scanning for candidates’
genes underlying a pulp yield QTL in Eucalyptus
globulus
Funding institution: FCT
Coordinator from INESC-ID: Ana Teresa Correia
de Freitas
Short Summary: The main objective is to identify and characterize the genomic region that underlies strong effect pulp yield QTL in E. globulus,
combining map-based cloning and transcriptomic approaches. Knowledge of the genomic
loci responsible for quantitative variation of wood
traits of interest (pulp yield), is of major interest in
molecular assisted breeding. This will allow identifying genes responsible for that variation, and
gathering new knowledge about the molecular
mechanisms of gene expression and regulation
in wood forming tissues.
Title: STOP-FIRE - A Computational Intelligence
Distributed System for Forest Fire Combat Aid
Funding institution: FCT
Coordinator from INESC-ID: João Paulo
Baptista de Carvalho
Short Summary: The main goal of this project
is the development of a computational intelligence based distributed system prototype that
can produce contingency plans to control and
combat forest fires based on available resources
(water, equipment, aerial and terrestrial vehicles,
firemen, etc.) and geographical, topological and
meteorological restrictions. The prototype will
be composed of several modules: an intelligent
graphical forest fire propagation simulator; an
expanded fuzzy GIS (Geographical Information
System) associated to a Data Mining system that
extracts geographical and topologic relevant
data; an Intelligent Data Mining system to extract
relevant available forest fire combat resource
data; an Expert system that provides contingency plans based on meteorological data, real time
constraints and information provided by the previous modules. All modules are components of a
web based distributed system that should provide good performance and remote accessibility.
Title: FLEETMOD - Modelling and Simulation of
the Behaviour of Fishing Fleets
Funding institution: FCT
Coordinator from INESC-ID: João Paulo
Baptista de Carvalho
Short Summary: Fishermen are the most important predators in marine ecosystems, with a high
impact on the mortality on marine populations
and destruction of marine habitats. In this project we aim a qualitative model of this predatory
behaviour, that will allow to simulate and predict
the responses of the skippers of fishing vessels
to a wide range of relevant factors, whether of
natural or human origin. This model will then be
connected to existing models of the population
dynamics of different fish stocks, and will provide
a framework to test the effectiveness of different
management measures, such as catch restrictions, marine closed areas, seasonal fishing bans,
etc. The project will focus on the bottom-trawl,
purse-seine and deep sea longline fishing fleets,
and will combine recent advances in qualitative
modelling techniques (rule-based fuzzy cognitive maps) with a privileged source of real-time
information on the behaviour of skippers taken
onboard during fishing trips.

Short Summary: The objective of this project is
to develop an innovative architectural framework
for handling risk in e-voting systems, addressing
three areas of concern: security-related risks,
community-related risks, and usefulness-related
risks.
Title: POLIGRID - distributed policies for
resource management in Grids
Funding institution: FCT
Coordinator from INESC-ID: Paulo Jorge Pires
Ferreira
Short Summary: The main objectives of this
project is to design a platform that supports the
definition, deployment and enforcement of distributed history-based policies in a scalable and
effective manner. In addition, we will provide a
prototype implementation that proves the feasibility of the concept and evaluate its performance
based on the simulation of selected grid usage
scenarios. To achieve the above mentioned goal
there are several challenges that must be addressed. As a matter of fact, in spite of being
used for a number of applications, grid platforms
still present a number of limitations in what concerns the enforcement of advanced usage models. In this project we will address the following
challenges: large number of users and distributed resources, resource heterogeneity, autonomous administrative domains, high volatility and
support for multi-level usage policies.

Title: REDICO - Dynamic Reconfiguration of
Communication Protocols
Funding institution: FCT
Coordinator from INESC-ID: Luís Eduardo
Teixeira Rodrigues
Short Summary: The Redico projects intends to
build a new protocol composition and execution
framework tailored to support dynamic reconfiguration. There are multiple challenges in addressing the problem, including:
- The new framework should support the seamless reconfiguration in run time. In particular,
it should allow for different participants to run
with different protocol configurations as long as
these configurations are compatible.
- The framework should provide strong support
to ensure the consistency of the system configuration (at each site and among multiple sites).
These consistency checks should be based on
protocol dependencies and should be able to
be checked in an efficient manner, to prevent
the performance degradation of the system.
In addition to building a new protocol framework,
the project aims at:
- Refactoring the existing group communication
protocol suite to work on the new kernel.
- To design a new group communication protocol
suite able to operate on hybrid networks, consisting of fixed (wired) nodes and mobile (wireless) nodes.
Title: GINGER - A Flexible Peer-to-Peer Grid
Infrastructure
Funding institution: FCT
Coordinator from INESC-ID: Rodrigo
Seromenho Miragaia Rodrigues
Short Summary: To build a fully decentralized,
peer-to-peer Grid infrastructure that meets several goals that are not met by current Grid infrastructures, such as ease of deployment and use,
lack of centralized components, or the ability
to run in an environment where nodes may not
be willing to cooperate, and where failure is the
norm, and not the exception.
Title: MERCURY - improving consistency of
replicated data in resource-constrained devices
Funding institution: FCT
Coordinator from INESC-ID: Paulo Jorge Pires
Ferreira
Short Summary: The high-level overall goal
of this project is to improve users’ productivity
by supporting data access with high availability and performance. Optimistic replication is a
well known technique to attain such goal but its
usefulness strongly depends on the underlying
consistency protocol to ensure fast and reliable
replica consistency.
This project will develop new algorithms, protocols, and system architectures running in prototypes that will ensure conflict minimization and
rapid update convergence appropriate for resource-constrained devices.
The contributions will be in the area of consistency
of replicated data. In particular: i) a consistency
protocol that decouples consistency information
from data propagation, thus minimizing network
bandwidth, ii) voting-based update protocols allowing rapid commitment in the presence of failures or partitions, and iii) content-based indexing
for structuring the data allowing the use of similarities between data, thus reducing memory usage.
Title: PASTRAMY - Persistent and highly
Availabe Software TRansactional MemorY
Funding institution: FCT
Coordinator from INESC-ID: António Manuel

read access to objects. We plan to support
several persistent store structures that allow
optimized access from STM and readable access from final users.
- To design and implement a collection of replication strategies tailored to build a reliable and
distributed STMs. Such algorithms are fundamental to increase the scalability and availability of STMs based systems. We plan to leverage
on the partner experience in building replication
algorithms for relational database models, to
build novel algorithms, adapted to the unique
characteristics of STMs.
- To deploy and evaluate the solutions above in a
realistic setting, using a open-source university
management system that is currently used at
the IST to incorporate all on-line campus activities and related management services.

Title: SHAMAN - Sustaining Heritage Access
through Multivalent ArchiviNg
Funding institution: European Commission
– FP7
Coordinator from INESC-ID: José Luis
Brinquete Borbinha
Short Summary: The aim of the SHAMAN
Integrated Project is to develop a next generation digital preservation (DP) framework. It is
furthermore developing corresponding preservation tools for analyzing, ingesting, managing, ac-
cessing and reusing information objects and data
across libraries and archives. Three prototypical
applications will support trialling and validating of
the result in scientific publishing, parliamentary
archival, industrial design and engineering and
finally experimentally also in scientific application
domains. To achieve these goals SHAMAN is applying grid-based multivalent, linguistic, semantic, and pier-to-pier methods for supporting DP
within its core infrastructure. To archive this, the
core functions are organized within the SHAMAN
reference architecture. The core services of the
SHAMAN framework are constructed by integrating Data Grid, Digital Library, Persistent Archive,
Context Representation, Annotation, and
Preservation as well as Deep Linguistic Analysis
and corresponding Semantic Representation
and Annotation technologies for simple and connected data types establishing, document, media, CAD, and scientific data, knowledge, and
information collections.

Title: ONTO-SEAWEB - Ontology Engineering
for the Semantic Web
Funding institution: FCT
Coordinator from INESC-ID: Helena Sofia
Andrade Nunes Pereira Pinto
Short Summary: This project is going to address
two goals:
1- Regarding ontology learning, the goal is to develop the required techniques to build an ontology about the structure of technical articles in a
semi-automatic way.
Since we aim at semi-automatic processes,
besides the construction itself, the task of processing source files can be automated. This will
allow processing large amounts of information.
Among the applications of this work, there is
the annotation of documents, allowing more
powerful search forms, and the transformation
of documents into other more structured formats.
2- Regarding risk analysis we are going to work on
pilot experiences of controlled ontology building processes to identify and abstract the most
critical risks that can affect them and identify
the necessary measures and guidelines to prevent them.
This will increase the success rates of these
processes.

Title: CLAW - Aprendizagem e Anotação
Cíclicas da Web
Funding institution: FCT
Coordinator from INESC-ID: Helena Sofia
Andrade Nunes Pereira Pinto
Short Summary:
We divide this project into two major objectives:
1- We propose a generic framework for profiling of
ontology learning techniques. This framework
is composed of two kinds of knowledge-based
components: a tutor and a learner. The tutor
is provided with a populated ontology, and its
task is to provide the learners with assertional
knowledge (i.e., individuals and the relations
between them).
2- Manually designed and automatically learned
ontologies can be used for the annotation of
the Web. A current short-coming of existing annotation tools is the inability to extract relations.
Entities are annotated but relations between
entities are disregarded. We propose a framework for the development of relation extraction
algorithms. Given an ontology and a document
whose named entities have been annotated
with the ontology, different algorithms will be
developed within the framework for the automatic instantiation of relations among entities.
This framework, when coupled with annotation
tools, produces both concept and relation instances.

that we will develop them in more text intensive
social tagging systems like digg and apply them
to our system.

Short Summary: LIREC aims to establish a multifaceted theory of artificial long-term companions
(including memory, emotions, cognition, communication, learning, etc.), embody this theory
in robust and innovative technology and experimentally verify both the theory and technology
in real social environments. Whether as robots,
social toys or graphical and mobile synthetic
characters, interactive and sociable technology
is advancing rapidly. However, the social, psychological and cognitive foundations and consequences of such technological artefacts entering
our daily lives - at work, or in the home - are less
well understood.
Successful technology can only be delivered on
the basis of strong scientific foundations, and
with partners in psychology, ethology, humancomputer interaction, human-robot interaction,
robotics and graphical characters, LIREC will
advance understanding of the concepts of embodiment, autobiographic memory and social
interactions in the context of companions where
the ‘mind’ might migrate to differently embodied
‘bodies’.

Title: PCL NOISE - Noise Reduction in Power
Line Communications Channels
Funding institution: FCT
Coordinator from INESC-ID: Paulo Alexandre
Crisóstomo Lopes
Short Summary: To develop new signal processing techniques and algorithms for noise reduction in the power line channel, and increase
the achievable bit rate. Only this way it can be
competitive with other technologies.
Power line signals are mostly limited by electrical compatibility issues, namely by the radiation
levels created by common mode currents in the
lines, it follows that it is important to minimize
injected currents, and not necessarily the voltage levels in the line. This can be done by taking into account the differences in impedances
between the noise sources and the emitter, and
requires the power line to be modelled as a two
port network. Another means for noise reduction
if to use the correlation between noises signals
in adjacent carriers. Still, another means of noise
reduction, that may be suitable for impulse, nongaussian noise, is the use non linear filters at the
reception to filter impulse noise. This can be done
throw voltera filters, neural network, or any kind
of non-linear filter.

Algorithms
Funding institution: FCT
Coordinator from INESC-ID: Pedro C. Diniz
Short Summary: This project aims to develop
and evaluate methods for the automatic mapping
of image processing algorithms to FPGA-based
hardware platforms. These methods must take
into account the limited resources on each FPGA

analyses techniques to analyze the opportunities
for data reuse and vectorization. We will develop
novel compiler analyses and mapping algorithms
to exploit compiler-controlled caching of data
and the development of custom vector pipelines
in FPGAs. Another novel aspect will be the inclusion of bandwidth and real-time constrains in the
design space exploration of alternative designs
enabled by the extreme flexibility of contemporary FPGAs.

Title: AMADEUS - Aspects and Compiler
Optimizations for MatLab System
Development
Funding institution: FCT
Coordinator from INESC-ID: João Manuel
Paiva Cardoso
Short Summary: MATLAB is regarded as a high
productivity language contributing to innovative
achievements in different areas. However, in the
presence of models requiring long simulations,
the developer has to code specific portions of the
models in less abstract languages (e.g., C). This
hampers the high productivity promise, decreases progress, and is also visible when MATLAB
specifications are targeted to embedded systems, increasing product development cycles.
This project intends to address aspect-oriented
extensions to MATLAB in order to help system
modeling and exploration of certain features
conceiving system implementation. Aspect mining will be used in order to acquire some aspects
relevance from third party MATLAB code.
We hope to identify aspects that will help optimization phases in order to generate performance
and memory efficient implementation code.
Code optimizations will be researched in order to
inference types, array dimensions and sizes, and
memory minimization.
A prototype weaver will be developed in order to
evaluate the ideas with complex MATLAB code.

216366
Coordinator from INESC-ID: Augusto Julio
Domingues Casaca
Short Summary: Future networks became a
central topic with a major debate concerning
whether moving towards the new networked society will be evolutionary or disruptive. In the future networked society, the physical and digital
worlds will merge based on the massive usage
of wireless sensor networks. Objects will be able
to identify and locate themselves and to communicate through radio interfaces. Self-organized edge networks will become more and more
common. Virtualization and programmability will
allow for providing different networking environments over the same infrastructure. Autonomic
networking will deal with the increasing complexity of I&C systems. End-user empowerment will
increase with their capacity of providing services
and content.
This new environment forces the scientific community to develop new principles and methods to
design/dimension/control/manage future multitechnology architectures. The new paradigms
raise new challenging scientific and technological
59
problems embedded in complex policy, governance, and worldwide standards issues. Dealing
with the diversity of these scientific and socioeconomic challenges requires the integration of
a wide range of research capacities; a role that
Euro-NF will fulfil.
Indeed, Euro-NF extends, in scope and duration,
the successful Euro-NGI/FGI NoE that has integrated the required critical mass on the networks
of the future and is now a major worldwide player
in this area. The consortium has evolved in order
to have an optimal coverage of the new scope.
Euro-NF will therefore cover the integration of a
wide range of European research capacities, including researchers and research and dissemination activities. As such Euro-NF will continue to
develop as a prominent European center of excellence in Future networks design and engineering,
acting as a “Collective Intelligence Think Tank”,
representing a major support for the European
Society leading towards a European leadership
in this area.

Title: MIA-VITTA - Mitigate and assess risk from
volcanic impact on terrain and human activities
Funding institution: Bureau de Recherches
Geologiques
Coordinator from INESC-ID: Teresa Maria Sá
Ferreira Vazão Vasques
Short Summary: The MIAVITTA project aims at
developing tools and integrated cost effective
methodologies to mitigate risks from various hazards on active volcanoes (prevention, crisis man-
agement and recovering). Such methodology will
be designed for ICPCs contexts but will be helpful for European stakeholders to improve their experience in volcanic risk management. The project multidisciplinary team gathers civil defence
agencies, scientific teams (earthsciences, social
sciences, building, soil, agriculture, Information
Technologies and telecommunications) and an IT
private company.
Title: FI-DRA - Analysis of the Distributed
Resolution of Feature Interactions for Internet
Applications
Funding institution: FCT
Coordinator from INESC-ID: Rui Gustavo
Nunes Pereira Crespo
Short Summary: In this project we intend to enlarge and conclude the research of an innovative
distributed system for FI resolution in Internet,
whose first part was concluded in 2005. The
proposed system represented a solution of FI
of internet applications, which alone satisfy requirements but togheter reveal undesirable behaviours. The project focus on the fundamental
properties of security use of the system, and on
the resolution reach for any non-empty set of
features candidates for execution. The properties
are formally identified and the results will be used
for a PhD thesis of one participant in this project.
Furthermore, the project focus on the capacity
enhancement that allows a single advisor to be
used by all application nodes in a local area. This
goal represents the major part of a MsC thesis of
one participant in this project. The project results
are expected to provide a basis for its adoption
in local are networks and Internet service providers.
Title: E2E-WSN - End-to-end Reliability in
Wireless Sensor Networks
Funding institution: IST - FP6
Coordinator from INESC-ID: Paulo Rogério
