Supporting collaborative work on ontology learning from Relational Databases

We present in this paper, one important feature of our approach that draws on a semantic enrichment process of the RDB model for learning application ontologies from Relational Databases (RDB)s. In fact, our approach supports collaborative work on the enrichment process and considers the partitioning of the input RDB model into a set of business modules. The objectives behind the collaborative support are threefold: (i) to allow each user to work on the RDB part that fits his/her domain knowledge; (ii) to save time in manual semantic enrichment; and (iii) to make easiest human evaluation of the ontology. We present the principle behind our approach, its features and its benefits.
