Incremental Generation of Mappings in an Ontology-Based Data Access Context

Ontology-Based Data Access provides a conceptual view over data repositories and mediates the access to this information. The cornerstone of this approach consists of a set of mappings which express relationships between repository entities and ontology elements. In practice, these mappings may incorporate constant values. We propose a (semi) automatic solution that derives new mappings by analyzing the intensional and extensional levels of the sources as well as previously defined mappings containing constant values. Our solution also generates concept and role labels associated to the newly proposed mappings and proposes a graphical user interface for their adoption/rejection.
