摘要
为实现Web服务的动态组合及管理,分析了该领域的研究现状,针对存在的问题,运用形式概念分析相关理论来研究Web服务的组合管理,对候选Web服务的输入输出数据关系进行形式化建模,有效地利用消息依赖关系实现服务的组合请求。提出了利用二分图求得所有形式概念的算法,建立服务格及计算服务组合关系的算法,设计并实现了原型系统以满足Web服务的动态组合及管理。
To implement dynamic composition and management of web services, the situation of study on this domain is reported. Aimed at these existing problems, using relevant theories of formal concept analysis to study web services composition and management. Modeling the input and output data relations dependency of candidate web services, then implemented the requests of services composition by use of messages＇ dependency validly. Some algorithms including finding all of the formal concept make use of bi-graph, building services lattice and calculating relations of services composition are designed. Lastly, a prototype system is designed and implemented to satisfy web services dynamic composition and management.
