Conception et prototypage d'un outil web de médiation et d'aide au dialogue tchaté écrit en langue seconde

Abstract : Our general research topic concerns computer-assistance to chat in a second language, spoken and/or writen. This thesis focuses on the definition and study, through a corpus and a prototype, of informatic assistants for written conversations (chat) in a second language, in a low mediation context. We present first what is "ordinary" chat in first language, the differences of surface and deep similarities towards other forms of writing. Then we show the limitations of current tools, with "strong mediation", in which the tool is interposed between speakers supposedly totally unable to communicate by other means, and that does not consider the case where the speakers may use an intermediary language. We adapt the scenario of Verbmobil project (1992-2000) for chat, and propose an approach with "low mediation" for partially bilingual speakers, able to take into account their skills and their specific problems. With the prototype developed in this view, Koine, we can study the informatic, ergonomic and linguistic constraints of such a system, and propose solutions and experiments. Koine is a Web service, which incorporates useful features to overcome barriers of communication in non-native language, such as whiteboard, interactive customizable phrasebook, MT pretranslation, measures of intelligibility and prototypicality, and possibility of "interactive and participative disambiguation."
