摘要
自动地根据用户请求进行服务的动态组合是目前Web服务领域的关键问题。针对该问题,提出了一种基于本体的服务动态组合方法,设计并实现了一个服务动态组合原型。首先Web服务按照一定规则被抽象为本体模型,然后通过分析所构造服务的模型来实现服务的匹配,最后利用BPEL4WS对匹配生成的服务组合序列来进行自动的组合。实验结果表明,该方法细化了服务接口的语义,并且在发现结果上有更高的准确性。
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 the method generates the plan and converts it into BPEL4WS that can be executed and return result to users. The experimentation the method specifies the semantics of web services and has a more accurate matchmaking result.
