Alignement automatique de textes parallèles Français-Japonais

Automatic alignment aims to match elements of parallel texts. We are interested especially in the implementation of a system which carries out alignment at the clause level. Clause is a beneficial linguistic unit for many applications. This thesis consists of two types of works: the introductory works and those that constitute the thesis core. It is structured around the concept of syntactic clause. The introductory works include an overview of alignment and studies on sentence alignment. These works resulted in the creation of a sentence alignment system adapted to French and Japanese text processing. The thesis core consists of two types of works: linguistic studies and implementations. The linguistic studies are themselves divided into two topics: French clause and Japanese clause. The goal of our French clause studies is to define a grammar for clause identification. For this purpose, we attempted to define a typological classification of clauses, based on formal criteria only. In Japanese studies, we first define the Japanese sentence on the basis of the theme-rheme structure. We then try to elucidate the notion of clause. Implementation works consist of three tasks which finally constitute the clause alignment processing. These tasks are carried out by three separate tools: two clauses identification systems (one for French texts and one for Japanese texts) and a clause alignment system.
