Génération de réponses en langue naturelle orales et écrites pour les systèmes de question-réponse en domaine ouvert

Abstract : The work presented in this thesis is in the context of question answering. Unlike many works dealing with information retrieval, our main problem is to characterize the possible form of an answer in interaction with the question and which could be produced by question answering systems. We present the case of answering a question considering two interaction modes : orally and in writing. Trying to define what could be an "in interaction answer" for question answering systems, we note the absence of a corpus of such answers. In order to constitute our own answers corpus, the question linguistic form used is important. A state-of-the-art study of questions linguistic variations is presented so. We present the corpus collection, both on oral and written modalities and performed with over 150 french native speakers, and an evaluation of the used protocol. Finally, we present an analysis of the collected corpus answering questions to be asked to implement a module for generating in natural language answers in a question-answering system.
