Extraction de termes, reconnaissance et labellisation de relations dans un th\'esaurus

TL;DR

This paper presents a method for extracting terms, recognizing relations, and labeling within a thesaurus to build a semantic structure for indexing, aiming to enhance geographic and conceptual integration.

Contribution

It introduces an approach to automatically construct an ontology from a thesaurus, incorporating geographic information and links between concepts.

Findings

Semantic structure creation from thesaurus data

Integration of geographic information via GIS

Automatic ontology building process

Abstract

Within the documentary system domain, the integration of thesauri for indexing and retrieval information steps is usual. In libraries, documents own rich descriptive information made by librarians, under descriptive notice based on Rameau thesaurus. We exploit two kinds of information in order to create a first semantic structure. A step of conceptualization allows us to define the various modules used to automatically build the semantic structure of the indexation work. Our current work focuses on an approach that aims to define an ontology based on a thesaurus. We hope to integrate new knowledge characterizing the territory of our structure (adding "toponyms" and links between concepts) thanks to a geographic information system (GIS).
