Construction et interrogation de la structure informationnelle d'une base documentaire en français

Abstract : This thesis presents an original methodology to identify and structure information of a French textual base in order to question it. Linguistic techniques in current methods make it possible to improve the results. So we propose a methodology using high-level linguistic analysis (morphology, syntax and word sense disambiguation) to identify each piece of information and to connect them. Because of the lack of context in queries, the texts are analyzed. Then, the information from lexico-semantic resources is used to transform each piece of information in many
realizations: simple and complex synonymy, derivation with adaptation to the syntactic context, addition of semantic features and categories... We finally tested the questioning method using a morpho-syntactic analysis to identify each piece of information in the question and to determine the semantic type of the required answer; the passage of the texts containing these data is the answer to the question.
