【摘要】 Web Services的自动合成要求其能用语义化的形式(比如本体)表示.如果能够把Web Services转化为本体的形式,就可以在合成中利用Web Services的语义,从而实现自动合成.把本体建模分为两个步骤来实现:输入输出参数建模和Web Services建模.首先提取Web Services的输入输出参数,将其表示为本体中类的形式,然后把Web Services对应于本体中的属性,定义类和属性之间的关系,通过这些关系来判断产生这些属性的Web Services之间的关系,再根据这些关系来确定Web Services能否合成.在此基础上,提出了一种基于本体的接口合成方法.更多还原

【Abstract】 The automatic composition of Web services requires the existing services to be encoded in a semantic form,such as ontology.If Web services are represented with ontology,Web services can be composed automatically by means of their semantics.Ontology modeling is divided into two steps:input/ output parameters modeling and Web services modeling.First,Web services’ input/output parameters are collected,and represented with classes in ontology,Web services are transformed to properties in ontology, relations between classes and properties are defined.Then decided are Web services’ relations based on relations between properties transformed from these Web services and it is estimated whether these Web services can be composed.Moreover,an interface composition method based on ontology is proposed.更多还原
