Analyse des discussions Homme-Homme en arabe

Abstract : This thesis deals with human conversations analysis specifically the Arabic political debates. The main objective is to study the argumentative aspects present in such discussions in order to identify conflicts, the exchange of opinions, acceptances and rejects of the ideas discussed throughout the dialogue. To perform this task, we focus on the recognition of dialogue acts which project the intention of the speaker and the context of utterance. We proposed an annotation scheme that reflects the communicative and argumentative structure of political debates. The proposed method is based mainly on the CRF models that take into account dependencies between words in the same utterance. These models were applied to the two tasks of segmentation and annotation of dialogue acts. The evaluation results are promising and confirm the effectiveness of CRF models for tasks of segmentation and labeling of sequential data.
