Recherche de relations spatio-temporelles : une m\'ethode bas\'ee sur l'analyse de corpus textuels

TL;DR

This paper introduces a novel method for enriching geographical ontologies by analyzing textual corpora to automatically detect spatial and temporal relations within journey descriptions.

Contribution

The paper proposes a new text analysis approach using lexico-syntactic patterns to identify spatial and temporal relations for ontology enrichment.

Findings

Successfully detected n-ary relations involving spatial and temporal aspects

Enhanced the geographical ontology with new relations derived from text analysis

Applicable to journey description corpora for ontology development

Abstract

This paper presents a work package realized for the G\'eOnto project. A new method is proposed for an enrichment of a first geographical ontology developed beforehand. This method relies on text analysis by lexico-syntactic patterns. From the retrieve of n-ary relations the method automatically detect those involved in a spatial and/or temporal relation in a context of a description of journeys.
