Abstract : This thesis deals with Natural Language Processing (NLP). It studies the iterative phenomena in French, and it covers the semantics of event repetitions within the same text, both in term of aspect and time. Our study is based on a teamwork focusing on multidisciplinary approach to the phenomena iterative guidance covering language, logic and science computer. This work is based on two common concepts: on one hand, a temporal entity called typical event that is presented as repeated over time, and on the other, we have the iteration itself, constructed as set of all occurrences of the model event. This thesis focuses on two aspects: the discursive inscription, basing on an object modeling for the construction of the meaning of iterations (Mathet, 2007); and the aspectual calculation through the semantics of temporality (Gosselin, 2011). We conduct, as a first step, a study corpus of newspaper articles and literature, which aims to characterize the discursive inscription of iterations. On this basis we expose their properties with a view towards automatically indentifying the iterations, i.e. matching the beginning and the closing of a textual segment. We establish also a model of annotation for this automation in order to instantiate iterations in the object model. In a second step, we consider the aspectual and temporal calculation of iterations. Based on the work of Gosselin on the aspectual calculation of selmefactive events, we study the adjustments in order to apply it to the iterative events, integrating the concept of two simultaneously independent referred aspectual, in view of the implementation process. Finally, we complete these two aspects of our work through the integration of our results in TimeML, an XML formalism for events and temporal expressions in natural language.
