Study on Extracting Sub-ontology from Multiple Ontology
多本体中子本体抽取的研究

There are many knowledge-souree-ontologies in departments of an enterprise. Partial content form multi-ontology, namely sub-ontology, is often used in an application. Current approaches to sub-ontology extraction mainly focus on single ontology. The authors analyze the main problems in sub-ontology extraction from multi-ontology, and propose a valid approach for extracting sub-ontology from multi-ontology. The approach reduces the complexity of sub-ontology extraction.
