SEME

SEMantics and Information Extraction (SEME)

Coordination: Cyril GROUIN

The SEME (semantics and information extraction) team is interested in the problems of accessing the meaning contained in language productions, for the purposes of analysis, comprehension, modeling or production. We apply our research to the written modality, without restriction on the original medium (text produced in electronic format, or from a speech transcription, or from optical recognition) and work on productions in open or specialized domains such as the medical field. We use both linguistic and statistical or neural learning approaches. We are particularly interested in the latter type of approach, and in the environmental costs they generate in automatic language processing, both during production and during use.

  • Information extraction
  • Corpus and modeling
  • Sémantics, poly-lexical expressions

The team comprises 10 permanent members (CNRS researchers, lecturers at Université Paris-Saclay, ENSIIE, and Université Sorbonne Paris-Nord), 14 PhD students, and 3 post-docs or fixed-term contracts. We maintain links with industry (theses under CIFRE contracts, research projects) and regularly organize scientific events (TALN conference, scientific workshops, etc.).
