【摘要】：Web服务技术为跨网络应用集成及构建复杂的业务流程提供了最佳实践,但基于XML的服务描述缺乏相应的语义信息,而当前的关于语义Web服务的研究大多集中于服务的功能性接口语义描述,已不能满足自动化服务计算发展的需要。本文设计了多维度语义Web服务的实现模型,细化了多维度语义Web服务的五个语义维度,定义了多维度语义的服务关系,并深入分析了从传统基于语法的Web服务到多维度语义Web服务的映射机制,提高了语义Web服务描述模型的可用性。其次,本文构建了异构多本体的语义支撑架构,以此对多维度语义Web服务进行语义增强,使得Web服务的描述不局限于单个本体,消除了Web服务之间语义的模糊性、理解的歧义性等问题,实现对Web服务全方位、多层次和多视角的语义描述。最后,本文设计并实现了基于多维度语义模型的Web服务开发工具,该Eclipse插件将多维度语义模型运用到实际中,支持直接开发多维度语义Web服务,同时,该工具能够检索服务网络中现有的多维度语义服务描述文档,为服务开发者提供共享的异构多本体,提高了服务开发的效率,提升了用户体验。与基于语法的服务发现结果对比,多维度语义Web服务的发现方法提高了服务发现的准确率,充分体现了多维度语义Web服务的优势。综上,本文设计并实现了多维度语义Web服务的开发工具,使得开发的Web服务符合多维度语义模型的定义,服务描述支持异构多本体,从而消除了服务的语义冲突。该开发工具有利于服务的共享与复用,为自动构建多维度语义的服务网络,实现自动的Web服务发现和组合奠定了基础。
[Abstract]:Web services technology provides best practice for cross-network application integration and complex business process construction, but the service description based on XML lacks the corresponding semantic information. However, most of the current researches on semantic Web services focus on the semantic description of the functional interfaces of services, which can no longer meet the needs of the development of automated service computing. In this paper, the implementation model of multi-dimensional semantic Web services is designed, the five semantic dimensions of multi-dimensional semantic Web services are refined, and the service relationships of multi-dimensional semantic Web services are defined. The mapping mechanism from traditional grammar-based Web services to multi-dimensional semantic Web services is analyzed in depth to improve the usability of the semantic Web services description model. Secondly, the semantic supporting framework of heterogeneous multi-ontology is constructed to enhance the semantics of multi-dimension semantic Web services, so that the description of Web services is not limited to a single ontology, and the semantic ambiguity between Web services is eliminated. Understanding ambiguity and other issues to achieve a full range of Web services, multi-level and multi-perspective semantic description. Finally, this paper designs and implements a Web services development tool based on the multi-dimension semantic model. The Eclipse plug-in applies the multi-dimension semantic model to the practice, supports the development of multi-dimensional semantic Web services directly, at the same time, The tool can retrieve the existing multi-dimensional semantic service description documents in the service network, provide the service developers with shared heterogeneous multi-ontology, improve the efficiency of service development and enhance the user experience. Compared with the results of service discovery based on syntax, the method of discovering multi-dimensional semantic Web services improves the accuracy of service discovery and fully reflects the advantages of multi-dimensional semantic Web services. In summary, this paper designs and implements a development tool for multi-dimensional semantic Web services, which makes the developed Web services conform to the definition of the multi-dimensional semantic model, and the service description supports heterogeneous multi-ontology, thus eliminating the semantic conflicts of the services. This development tool is conducive to the sharing and reuse of services, and lays a foundation for the automatic construction of a multi-dimensional semantic service network and the realization of automatic Web service discovery and composition.
