提出了将OWL和Horn子句相结合构建β-PSML语言,它既可以表示OWL中不能表示的多元关系,又可以表示Horn子句难以表示的有丰富等级结构的领域模型。提出的β-PSML语言是一种语义Web中新的知识表示方法,利用该β-PSML语言的推理功能可以完成语义Web中的查询。
In this paper, we propose to combine the OWL with the Horn clause to construct the β-PSML language, which can not only represent the multivariate relations that can not be expressed in OWL, but also represent the domain models with rich hierarchical structure that are difficult to be expressed by the Horn clause. The proposed β-PSML language is a new method of knowledge representation in Semantic Web. By using the reasoning function of the β-PSML language, the query in the Semantic Web can be completed.
