| 摘 要： | 可以把Web服务描述为一个关系，把Web服务的组合过程描述为关系间的运算．据此阐述了Web服务组合的关系模型，给出了相关定义，分析了一种用于消除合成语义冲突的领域级本体，给出了一种输入闭包的优化过程；通过建立服务组合序列，描述了Web服务组合方法，该方法简化Web服务的合成，具有无回溯、易于优化和易于实现的优点．

| Abstract: | A web service can be described as a relation,and the composition process of Web services can be described as relational operations.Under the idea,the relational model of Web services composition is explained,the relevant definitions are presented and the domain ontology for eliminating the composition semantic conflict is provided in the paper.Then the computing of the input closure is optimized and the process of Web services composition based on building the composition sequence is described.This composition approach simplifies the composition of Web service and has some characteristics,including non-backward,easy to optimize and easy to realize. |

| Keywords: | relational module ontology composition sequence Web services composition |
