The Design And Implementation Of Multiple Key Strategies In Ontology Mapping

The goal of semantic Web is to make Web data machine readable. As the number of ontologies keeps growing, ontology sharing and reuse become urgent problems. Mapping between different ontologies is the key to solve the problems of ontology communication and interoperation. The thesis focuses on research on these issues.Firstly, the background of Semantic Web research domain and current research situation of Ontology Mapping have been introduced. Then the module structure of ontology mapping system NewMapping is described.Secondly, aiming to the problem existing in the multi-strategies ontology mapping system, this paper proposes an improved method of multi-strategies mapping, it considers enough to the characteristics and semantic contexts of strategies, and makes use of multi-strategies to computing similarity in order to most using of ontology information.Based on the research above, ontology mapping sub-system NewMapping has been implemented. Moreover, the mapping effective of the system has been tested through using benchmarks, ontology set offered by OAEI. The precision, recall, and F-measure values have been statistically analyzed. The results show that our approaches are comparatively good.
