Indexation sémantique de corpus multilingues : application aux manuscrits anciens

Our study takes place in an European Project LIBRARIES named BAMBI (Better Access to Manuscripts and Browsing of Image). This paper presents a method for multilingual access information. Our approach uses a semantic structure in order to index a document without taking account of its language. This semantic structure is a hierarchical organisation of semantic elements. Each element contains two levels of description, rhetorical organisation and meaning representation. The meaning representation is based on a conceptual graph formalism. A semantic structure is used as an index for a document and its translations. We applied our method to a transcription of a medical manuscript dated from the eighteen century.
