Résolution des anaphores nominales pour la compréhension automatique des textes

Abstract : In order to facilitate the interpretation of texts, this thesis is devoted to the development of a system to identify and resolve the indirect nominal anaphora and the associative anaphora. Resolution of the indirect nominal anaphora is based on calculating salience weights of candidate antecedents with the purpose of associating these antecedents with the anaphoric expressions identified. It is processed by twoAnnexe317different methods based on a linguistic approach: the first method uses lexical and morphological parameters; the second method uses morphological and syntactical parameters. The resolution of associative anaphora is based on syntactical and semantic parameters.The results obtained are encouraging: 90.6% for the indirect anaphora resolution with the first method, 75.7% for the indirect anaphora resolution with the second method and 68.7% for the associative anaphora resolution. These results show the contribution of each parameter used and the utility of this system in the automatic interpretation of the texts.
