Abstract : Since the number of electronic textual documents keeps increasing, it has become more and more difficult for users to access information out of this amount of data.
That is why this thesis dealing with Natural Langage Processing aims to help users in such situations.
Existing systems (such as search engines on Internet) do not fully satisfy their users in repeated tasks, barely taking into consideration the users' points of view and their interactions with the textual material.
In this thesis, we propose to consider personalization and interaction as the core of new tools to access the content of sets of texts.
Thus, we represent users' points of view on domains they are interested in with sets of lexical units described and structured according to a differential lexical semantic model.
We, then, use such representations to build cartographic supports allowing interactions between users and their sets of texts in order to visualize gatherings, links and differences between texts in a set and, doing so, to reach their content.
To computerize such propositions, we have developed the ProxiDocs plat-form.
Many validations of the plat-form have been realized through multidisciplinary experiments, such as information retrieval on Internet and a study of metaphorical expressions.
All of them brought to the fore the efficiency of our propositions.
