PUBLIC MARKS from parmentierf with tags sémantique & ontologie

Thèse de doctorat (informatique) d'Alexandre Passant - 9 juin 2009

Our game is original, being the main objective to ease the semantic validation of any semantic relation previously extracted in any language. Using the results gathered from approved relations we made possible the automatic creation of an ontology.

The Bibliographic Ontology Specification provides main concepts and properties for describing citations and bibliographic references (i.e. quotes, books, articles, etc) on the Semantic Web.

EuroWordNet is a multilingual database with wordnets for several European languages (Dutch, Italian, Spanish, German, French, Czech and Estonian). The wordnets are structured in the same way as the American wordnet for English ( Princeton WordNet, Miller et al 1990) in terms of synsets (sets of synonymous words) with basic semantic relations between them. Each wordnet represents a unique language-internal system of lexicalizations. In addition, the wordnets are linked to an Inter-Lingual-Index, based on the Princeton wordnet. Via this index, the languages are interconnected so that it is possible to go from the words in one language to similar words in any other language. The index also gives access to a shared top-ontology of 63 semantic distinctions. This top-ontology provides a common semantic framework for all the languages, while language specific properties are maintained in the individual wordnets. The database can be used, among others, for monolingual and cross-lingual information retrieval, which was demonstrated by the users in the project.

Enfin un article clair, avec une définition claire de l'ontologie. Conformément à ce que je pressentais, un thesaurus est une forme d'ontologie. Merci à Karl pour cet article qui manquait (beaucoup de collègues se posent la même question).
