基于规则映射的Web服务自动组合

Web Services Automatic Composition Based on Mapping of Rules

针对目前多数Web服务组合流程需要人工设计的问题,提出一种基于输入输出参数与规则关联映射自动构建Web服务组合路径的方法。该方法首先给出产生式规则库,并对输入输出参数本体建模,然后从用户给定的输入出发,建立输入输出参数与规则相关联的映射表,在映射表中由用户期望的输出开始回溯找出所有满足条件的组合路径,最后根据服务质量描述,选取最优的组合方案返回给用户。

In light of the majority of Web services need to manually design,the approaches of automatically building a Web services path based on input and output parameters associated with the rules mapping are put forward.This method firstly gives production rule bases,and models ontology according to input and output parameters,then from the user＇s inputs to establish mapping table which associates input and output parameters with rules and to find out all combination of path that meet conditions.Finally the quality of service is described and the optimal schema is selected to return to users.
