Knowledge and Language Management

Presentation

All TALC teams work on the three closely related notions of document, language and knowledge. There are some common notions which are present in most of the teams.

In a wide range of contexts, computational semantics – i.e studying, building and reasoning with meaning is a common research area. Indeed, in document analysis, characters or symbols in a document could be considered as low level cues used and combined to build more complex entities. Speech recognition or sentence analysis studies semantics related to language. And, at a more “higher” level, discourse or knowledge representation require the study of logical formalisms, their expressive power, the mapping from one formalism to another, reasoning and proving.

Models are used in several teams of the TALC department: models of characters, of documents, articulatory models and language models, models of knowledge.

Many activities provide input or output to an end-user, for example in developing natural language-based interface, learning systems, or providing ontologies to experts of a domain.
