ONTOLOGICAL CLIQUES - Analogy as an Organizing Principle in Ontology Construction
Tony Veale, Guofu Li · 2009
Ontology matching is a process that can be sensibly applied both between ontologies and within ontologies. The former allows for inter-operability between agents using different ontologies for the same domain, while the latter allows for the recognition of analogical symmetries within a single ontology. These analogies indicate the presence of higher-order similarities between instances or categories that should be reflected in the fine-grained structure of the ontology itself. In this paper we show how analogies between categories in the same ontology can be detected via linguistic analysis of large text corpora. We also show how these analogies can be clustered via clique-analysis to create meaningful new category structures in an ontology. We describe experiments in the context of a large ontology of proper-named entities called NameDropper, and show how this ontology and its analogies are automatically acquired from web corpora. 1
