Method for web services dynamic composition based on expanded semantic interface

It is a sixty-four-dollar question that composing existing web services dynamically according to user's request.A dynamic web service composition method based on ontology is proposed and a system for service composition is designed.Firstly,web services are modeled based on ontology with some rules.Secondly,services are matched by analyzing the inner process of the service.Finally,the method generates the plan and converts it into BPEL4WS that can be executed and return result to users.The experimentation reflects,the method specifies the semantics of web services and has a more accurate matchmaking result.
