Study of Semantic Web-Oriented Ontology Integration Technologies
Wenjie Li · 2009
Considering structure and elements of domain ontology, and multi-granularity technique on ontology integration, an ontology integration tool for the same field is developed in this paper. Take example for two electronic ontologies, in which the structural features of OWL (Web Ontology Language) files are analyzed, from which the main information are extracted and displayed by tree structure. Through mapping methods both elements and structure levels, the similarity degree is calculated and ontological dictionary Wordnet is adopted to get lexical semantic relations, and statistical methods is used to eliminate the discrepancy between words, in order that make integration operation on domain ontology. The result indicates that the tool not only realizes integration on elements, but also fulfills analysis on semantic of domain ontology.
