摘要: 为解决当前网络服务缺乏有效查询机制的问题,最大化利用网络服务,提出一种基于语义网络的网络服务查询机制。在该机制中,采用本体描述网络服务的服务信息、领域相关和领域无关的基本概念信息,并结合已经实现的基于本体推理的面向Web分布式本体系统,引入领域规则,结合使用本体推理引擎F-Logic,实现了网络服务智能发现系统。同时,提出了网络服务约束模型(主体,属性,值,动作)和语义补充模型。最后,通过一个具体的实例,演示了该系统的推理过程和运行结果,说明了网络服务查询的自动化,并对相关工作进行了对比。

Abstract: To solve the problem of lacking effective services query mechanism in existing Web services and maximize the using of Web services, a semantic Web technology based Web services query mechanism was proposed. With this mechanism, the Web services related ontology information, domain dependent and independent basic conceptual ontology information were adopted. Combined with a former system Web Oriented Distributed Ontology System (WODOS) which supported ontology-based reasoning, a new system Web Services Intelligent Discovery System (WSIDS) based on domain rules and F-logic reasoning engine was implemented. At the same time,Web services constraint model: Subject, Property, Value, Action (SPVA), and semantic supplement model were proposed. Finally, an application case was used to illustrate reasoning process and running result of this system, and was also compared with other related tasks.
