摘要
W eb服务的有效管理是实现服务发现和服务组合的关键。文中定义了W eb服务及服务间的关系等基本概念,在W eb服务管理中引入了形式概念分析(FCA)的方法,建立了描述服务间相互关联的概念格,分析了如何通过概念格对W eb服务进行有效地管理,并实现了概念格的增量维护。对模拟数据和真实数据的相关实验表明,文中提出的基于概念格的方法能有效地实现W eb服务管理,提供了一种规范的对服务功能的分类管理策略,对服务发现也有较好的检索效果。
An efficient management of Web Services is the key to service discovery and service composition. Some basic concepts about Web services are introduced, the relationships between Web Services are defined. A concept lattice corresponding to the properties of Web services is generated to describe the relationships among different services. The management for Web services with concept lattice is discussed. An algorithm is developed to maintain concept lattice incrementally and to retrieve Web services successfully in the concept lattice. Extensive experiments show that Web services could be managed effectively and retrieved with high efficiency and accuracy when using the proposed approach.
