Semantic Relations for an Oral and Interactive Question-Answering System.

Résumé

RITEL is an oral and QA dialogue system, which aims to enable a human to refine his research interactively. Analysis is based on typing of chunks, according to several categories: named, linguistic or specific entities. Since the system currently obtains promising results by using a research based on a common presence of the typed chunks in the documents and in the query, we are expecting better score quality by detecting semantic relations between the chunks. After a short description of the RITEL system, this paper describes the first step of our research to define and to detect generic semantic relations in the user's spoken utterances, by coping with difficulties of such an analysis: necessary quickness, recognition errors, asyntactical utterances. We also give the first results we have obtained, and some perspectives of our future works to extend the number of detected relations and to extend this detection to the documents.
