Un environnement basé sur la logique pour développer des applications du traitement automatique du langage naturel

摘要

We present a system providing a set of tools for developing natural language processing (NLP) applications such as natural language interfaces, communication aid systems, etc. This system is based on two principles : modularity of knowledge representation to ensure the portability of the system, and guided sentence composition to ensure transparency, i.e. to ensure that the produced sentences are well-formed at the lexical, syntactic, semantic and conceptual levels. We first describe the formalisms we have defined for knowledge representation. Then we explain how guided sentence composition is carried out. Finally, we give several examples of applications developed from this system.
