The method for processing data in a relational database wherein ontology data that specifies terms and relationships between pairs of said terms expressed in an OWL document is stored in the database, database queries that include a semantic matching operator are formed which identify the ontology data and further specify a stated relationship between two input terms, and the query is executed to invoke the semantic matching operator to determine if the two input terms are related by the stated relationship by consulting said ontology data.

La présente invention a trait à un procédé pour le traitement de données dans une base de données relationnelle dans lequel une donnée d'ontologie qui précise des termes et des relations entre des paires desdits termes exprimés dans un document OWL est stockée dans la base de données, des interrogations de base de données comprenant un opérateur d'appariement sémantique sont formées qui identifient la donnée d'ontologie et précisent davantage une relation exprimée entre deux termes saisis, et l'interrogation est exécutée pour invoquer l'opérateur d'appariement sémantique en vue de déterminer si les deux termes saisis sont associés par la relation exprimée en consultant ladite donnée d'ontologie.
