Abstract

The invention provides a large-scale Chinese ontology-oriented mapping method. The method includes: a concept initial correlation degree calculation method based on the fusion of synonyms and edit distance similarity algorithms; a quasi-nuclear force field potential function based on the improved fusion of concept similarity and dissimilarity based on the initial correlation degree. Compress the scale of large-scale ontology mapping; measure the similarity of complex concepts in Chinese ontology by introducing a global sequence alignment algorithm. Due to the phenomenon of polysemy and word order sensitivity in Chinese words, and the computational overhead of large-scale ontology mapping is very large, and the present invention first improves the existing quasi-nuclear force field potential function so that the measurement of the similarity between concepts and the to-be-mapped Ontology scale reduction is more reasonable. Secondly, the global sequence alignment technology is used to map complex Chinese concepts, and then improve the defects of the existing Chinese ontology mapping system, and finally improve the mapping efficiency, precision and recall of the system.

Description

technical field

[0001] The invention relates to the field of Chinese ontology mapping. Background technique

[0002] The vision of the Semantic Web is to build a "Web of Data" (Web of Data) to enable machines to understand semantic information on the Web. Ontology, as the core element of Semantic Web, is a formalized and standardized description to describe shared concepts in a specific field, and is the basis for realizing network knowledge sharing and semantic interoperability. At present, due to the heterogeneity among different ontologies, it becomes difficult to reuse and share between ontologies.

[0003] The task of ontology alignment (Ontology Alignment) is to discover the conceptual semantic association between heterogeneous ontologies. However, due to cultural and background reasons, there is still a lack of a mature ontology mapping system for Chinese language description. With the development of the Semantic Web, large-scale ontology and knowledge bases descri...
