Do competency questions for alignment help fostering complex correspondences?
Résumé
The Linked Open Data is composed linked knowledge bases. Most of these links are still limited to simple correspondences. As a complement, complex correspondences bring more expressiveness to bridge the heterogeneity of knowledge bases. Finding correspondences (simple or complex) is the purpose of ontology matching. Existing matching solutions mainly focus on establishing as many correspondences as possible given two knowledge bases. On the one hand, this has the effect of neglecting the user needs. On the other hand, when dealing with large knowledge bases, this may impact the performance of the matching task. In response to this observation, we introduce Competency Questions for Alignment (CQAs) to express the needs of a user with respect an ontology alignment. We present our work on how CQAs can help ontology matching, and in particular complex matching.
