Debugging is-a structure in networked taxonomies
Patrick Lambrix, Qiang Liu · 2011
With the proliferation of ontologies and their use in semantically-enabled applications, the issue of finding and repairing defects in ontologies has become increasingly important. In this paper we address the problem of defects in the is-a structure of taxonomies, the currently most frequently used kind of ontologies. We deal with both missing is-a relations as well as existing wrong is-a relations. The context of our study is a taxonomy network consisting of taxonomies networked by correct mappings. We propose a semi-automatic ontology debugging approach, which supports domain experts in debugging the is-a structure in taxonomies. We develop algorithms to detect and repair wrong and missing is-a relations. Further, we discuss an implemented system, RepOSE, and an experiment on real-world ontologies.
