Questions réponses et interactions

Abstract : The question answering systems monolingual or multilingual allow to look in a large collection of documents (of journalistic type for example), or on Web an answer specified to a question. However, there is no possible interaction after the answer: we cannot ask for a precision, modify the question. Now often the answer cannot be directly brought ( too indistinct question), or is not completely satisfactory for the user. The subject of the thesis consists in spreading these works so as to allow a user to start a real dialogue, which is not reduced to a question/answer, by basing itself on works led within the framework of the man-machine dialog. The context of this thesis is situated in the continuation of the works led in the group LIR of the LIMSI. Indeed, we work for several years on the systems of Question-answering, and we participated in several campaigns of evaluation, so much on monolingual English (campaign TREC-QA: http: / / t rec.nist.gov/), that on monolingual French (campaign EqueR-EVALDA: http: / / www.elda.org / article118.html) or on the multilingual (campaign CLEF-QA: http: / / key qa.itc.it/). These campaigns present the interest to allow an evaluation of our works with regard to the national and international community. They also allowed us to measure the limits and to define very opened fields of research, whether it is at the level of our group or perspectives envisaged in the frame of these campaigns of evaluation. Besides, we worked for a long time on the systems of man-machine dialog, more or less finalized. The frame of the opened systems (without task defined) which establishes the search in large collections of documents or on Web allows us to resume and to spread these works. The purpose of this thesis is to open the systems of question / answer to a dialogue during which any subject can be approached. The point of departure is an adaptation of the works led in man-machine dialog in domains restricted to a Question answering system. These researches have for purpose to bring new perspectives to the search engine of classic information, at at the same time in term of precision of the found information, the volume of information treaties and of saving of time to reach this information.
