We will analyze problems related to this technical documentation via our methodological approach starting from a linguistic analysis to find the relevant themes, and from a logical analysis of the discourse conveyed by the texts, by exploring the links between the textual elements intra- sentence. According to an approach where the documentary universe conveys informational and communicational operations. We describe an analysis to delineate the formal frameworks of documents and their exploitation for an optimal reorganization of the information contained in the documents of the French Social Affairs Administration (MDPH).

In order to identify specificities in the technical texts to propose a navigation prototype with a thematic tree structure, we propose a model of knowledge representation (three classificatory universes) to guide the discursive analysis. The transversal themes allow intra-documentary navigation between textual blocks. The inter-proposal themes allow to finely index the informational content (co-reference, implication, causality, etc.) of a document by its composite structure. We distinguish tree universe : ‘productive universe of administrative documents ‘, ‘Contextual universe of intra-document sequential blocks ‘, and ‘reference universe of the informational discourse of themes and logical relations’; Our recommendations based on our analyzes are summarized in the tree structure above, which reproduces the procedures to accompany a speaker in the search for a optimized path. We can immediately distinguish the fallout from such a tree-like result for programming. This tree is used to refine the process of entering information.
