Comment peut-on construire une ontologie personnelle à partir de textes ? Considérations linguistiques

This paper deals with personal ontologies construction from texts using a linguistic point of view. It aims to emphasize differences between personal ontology and local ontology. The points examined are variations concerning ontology structure itself but mainly, characteristics concerning corpora used for ontologies construction. Three corpora (two handbooks and a corpus of interviews) are compared, examining first some linguistics features and then conceptual relation patterns. The comparison leads to the conclusion that the construction of a personal ontology from texts, if not impossible, raises issues much more difficult than the construction of local ontologies, because it may be difficult to clarify how the individual writer takes into account his/her own position in his/her discourse.
