Ontology is a conceptual model, which is used on data exchange between heterogeneous data sources in semantic web, and liked by many people. Because of the shortage of the uniform standards for constructing ontology, it brings in lots of problems of ontology heterogeneity. Ontology mapping aims at these problems, and semantic similarity between ontologies is the key part of ontology mapping. In this...
In order to solve problems of semantics recognition and information extraction in the process of service composition, we proposed a Petri Net model of semantics service composition based on Ontology. Firstly, which build a described approach of semantics service composition ontology-oriented, and exploits property of WSMO to describe; Secondly,build Petri Net model of semantics service composition,...
Nowly, ontology been successfully exploits information extraction and semantics of message processing, language have OWL-S and WSMO based on ontology, But OWL-S is most exploited, WSMO is still located for stages of development , Therefore, firstly, analyze similarities and differences between OWL-S and WSMO, Secondly, analyze and research application method of WSMO form angle of theroy, Finally,...
