Nathalie Aussenac-Gilles - DR2 CNRS at IRIT, UMR 5505 , Toulouse, France


Nathalie Aussenac-Gilles is a CNRS senior researcher at IRIT, the laboratory in Computer Science of Université Paul Sabatier in Toulouse, since 1991. She is currently heading the IA department at IRIT together with P. Zaraté. Before, she headed the MELODI group (http://www.irit.fr/-Equipe-MELODI- ) jointly with P. Muller from 2011 to 2020 and from 2010 to 2019, she coordinated activities at IRIT related to Big Data, AI and Data processing.

Her research deals with knowledge engineering (KE) and semantic web technologies, methods and models for ontology engineering and population from human expertise, text and more recently from data. She contributes to information extraction from text, in particular relation extraction, and ontology-based integration of heterogeneous geospatial data. Her work is influenced by long term cross-disciplinary collaborations with linguists and researchers in human factors. She designed methods and platforms for ontology engineering and evolution, tools for semantic relation and concept extraction from text, as well as on knowledge representation to include lexical data.

She has been task manager in various French ANR and FUI projects with applications in areas as diverse as archaeology, car diagnosis, cartography, Earth observation or scholar paper analysis. She is an expert for the French ANR program, and was membre of the CNRS recruitment and evaluation committee from 2008 to 2012 and from 2016 to 2021. She chaired the GRACQ (1988-2005), a French working groups in KE, and later the TIA SIG (2005-2010) in NLP, KE and terminology. She was involved in the organization or chairing of conferences (EKAW, ESWC, TIA, IC, …) and she belongs to the editorial boards of scientific journals (formerly RevueI3 and IJHCS, currently Applied Ontology). She supervised 17 PhD. theses and published more than 90 papers in Journals, conferences and workshops related to semantic web and knowledge engineering.
