The SAMOVA group, via the integration of the ILPL group, has now a long standing experience in natural language processing. The approach pairs language, linguistics and reasoning, it covers the following fields:
- Lexical semantics of predicative forms: verbs (Volem Project) and prepositions (PrepNet project), emphasizing a conceptual approach, in a multilingual environment. More specific areas: analysis of the notion of predication in language, characterizing the notion of instrument, primitive-based languages for semantic representation, decompositional approaches to semantics and meaning, modelling sense variation and polysemy.
- Text syntax and semantics, syntactic formalisms for text structure, text semantics. Particular focus on: recognition of rhetorical structures, application to procedural text structure (TextCoop project); organization and expression of explanation and argumentation structures in texts.
- Formal models for language processing: underspecification, types and lambda-calculus for semantic representation computation, dealing with polysemy and sense variation based on type coercion and other forms of inference.
- application areas: text semantics and text tagging dedicated to procedural texts, question-answering applied to how-to questions, why-questions and opinion questions. Post-edition tools in Foreign language production to correct grammatical and style errors (with Toulouse II LLA lab, project CorrecTools).
