Overview

Research topics

I belong to the KID team (Knowledge and Image analysis for Decision making), which focuses its research on human operator confronted to complex systems. This team follows three axes: knowledge acquisition and modeling, image analysis and decision making. I am involved in the knowledge axe.
Involved within decision process, human operators often face up to huge data, that have to be analyzed and synthetized in a very short time. It is thus necessary to automate some cognitive tasks.
To this end, domain ontologies may be used as semantic guidelines, in several phases of this process:

Indexing and semantic navigation over multimedia data;
Knowledge and conceptual maps visualization and interaction;
Semantic measures calculus;
Conceptual Information Retrieval;
Identifying reliable information.

Using the graph structure of ontologies we proposed several efficient algorithms, for example for sub-ontology extraction, similarity estimation or information retrieval.

Collaboration

National collaborations
These works are conducted together with internal collegues, Jacky Montmain, Stefan Janaqi, Michel Crampes, Michel Plantié and academic partners, in particular with Vincent Ranwez.

International collaborations
Some works have also been developed in collaboration with Rovira i Virgili University and in particular David Sanchez and Montserrat Batet (2012-2014).
In spring 2014 Olivier Biberstein joined the team for 6 months.

Softwares

For our development contribution please visit:
Semantic Measure Library SML (developed by Sébastien Harispe)
Conceptual Information Retrieval applied to genes: OBIRS (developed by Mohameth François Sy)
Universal Semantic Indexer USI (developed by Nicolas Fiorini)
and for sub-ontology extraction (OntoFocus) or semantic distance (OntoDist) see the team website.
Some of our tools (OBIRS, OntoFocus) are also used within the PhylARIANE project or on the OrthoMam website

Industrial partnership

Historically close to industry, our lab manages its research in response to partners problematics within european or national project (French ANR/RIAM), rigional ones (Languedoc-Roussillon region) or through technologic incubator of école des mines d’Alès.
Here some of our industrial or academic partners: e.+, Solunea, Owanis consulting (projet DOCALIS), Inserm (for which we developed collaborative plateforms for ITS, IHP or Cancer), CEA (see the collaborative platform ToxNuc), Nétia, I-Nova, SAP CEC Karlsruhe.
