National Contracts


Keywords : reconfigurable architecture , FPGA , genomics .

Participant : Laurent Amsaleg.

Joint work with SYMBIOSE, ADEPT and R2D2.

The goal of this ACI is to provide a portal allowing the access to shared computing resources geographically distributed in order to boost bio-related algorithms (such as DNA alignments for instance). Our team is involved in the design of the architecture of the grid.

Action Bio-info inter-EPST: Parallel and Reconfigurable Architectures for Genomic Data Extraction

Keywords : architecture reconfigurable , FPGA , genomics .

Participant : Laurent Amsaleg.

Joint work with SYMBIOSE and R2D2.

This works aims at defining a specialized highly-parallel architecture devoted to process large amount of data such as genomics sequences. This architecture is based on FPGA. We are involved in its design.

Inter-EPST Bio-informatic Action Caderige-2: Automatic Document Categorization for the Extraction of Gene Interaction Networks

Keywords : Information extraction , bio-informatics , genomic data .

Participant : Pascale Sébillot.

Inter-EPST bio-informatic action from CNRS, INSERM, INRA, INRIA, Ministère de la Recherche, grouping people from Symbiose and TexMex teams at Inria, plus the following laboratories: Leibniz/Imag, LIPN, LRI, MIG/INRA and Inra-Ensar. This action, which has stopped at the end of October 2003, aimed at discovering within bio-informatic textual databases (MedLine), texts dealing with gene interactions, and at extracting the interaction networks from those texts. Our participation concerned the automatic detection of text segments that describe the interactions.


Keywords : Document analysis , information retrieval .

Participant : Pascale Sébillot.

This national action, coordinated by L. Romary (Loria), concerns information retrieval within electronic textual databases. Together with industrial firms, it aims at developing a software chain able to capture, analyze, and search through textual documents, using and grouping research solutions proposed by different INRIA teams.

ACI Masse de données MDP2P

Keywords : peer-to-peer , multimedia .

Participants : Laurent Amsaleg, Patrick Gros.

Joint work with Atlas, Gemo and Paris.

We investigate, in this 3 years project, how peer-to-peer (P2P) distributed architectures can be used to cope with the fast increasing volumes of numeric data (such as text and multimedia data) often stored in autonomous, heterogeneous and distributed equipments. The potential advantages of P2P systems are node autonomy, scale up to large numbers of nodes, high availability (through replication) and performance (through parallelism). Thus, the main objective of the project is to provide high-level services for managing text and multimedia data in large-scale P2P systems.

Our role in this project is focused on the management (querying and retrieval) of multimedia data.

ACI Masse de données REMIX

Keywords : architecture , very large main memory , image retrieval .

Participant : Laurent Amsaleg.

Joint work with Symbiose, R2D2 and Equipage (Valoria, Vannes).

The REMIX project proposes the design of a dedicated and very large RAM index memory (several hundreds of Giga bytes), big enough to entirely store huge indexes in main memory, avoiding the use of any disk. The use of an almost unlimited main memory raises completely new issues when designing indexes and allows to entirely revisit the principles that are at the root of almost all existing indexing strategies. Here, within this scheme, direct access to data, massive parallel processing, huge data redundancy, precomputed structures, etc., can be advantageously promoted to speed-up the search.

Our role in this project is focused on the design of main-memory oriented index structures dedicated to boost content-based retrievals.

ACI Jeunes Chercheurs TEXMEX

Participants : Laurent Amsaleg, Laure Berti-Équille, Patrick Gros.

This program of the French ministry of Research aims at helping the creation of new research teams by young researchers. In the frame of this program, Texmex received 103 kEUR for 3 years.
