Ontology-oriented Petri Net Model of Semantics Service Composition

摘要

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, which design grammar detected and semantics validated to implement the model in the process service composition, and apply greed genetic algorithm to optimize the model, which to meet demand of bussiness logic. Finally, in the Aciera Ontology Library (AOL), application and analysis showed that efficiency of service composition is better than tradition method, and implemented fuction is more precision.
