摘要: 要使Web资源支持资源的自动发现,首先需要对Web资源提供必要的描述。Web资源的元数据模型——资源描述框架只能表示资 源之间的二元关系,多元关系必须转化为二元关系后才能表示。然而多元关系与其转化为多个二元关系后所具有的语义是不相同的。针对资源描述框架存在的上述问题,该文引入本体论相互属性的概念,避免了不恰当地使用多个二元关系表示多元关系。同时给出了Web资源元数 据本体模型的XML标记库,使得描述Web资源的本体模型可以在Web网络上传输,并被搜索引擎解析和理解。

Abstract: The automatic discovery of information on world wide web demands the meta model for Web resource. The resource description framework is developed to meet such needs. Since the higher-degree relationship is not supported by RDF and the semantic meaning of higher-degree relation is not equivalent to its converted binary ones, this paper introduces the mutual attribute conception from ontology into Web modeling to avoid the problem of improperly representing higher-degree relation with binary ones. Additionally this paper shows how to define ontological meta model of Web resource in XML documents to enable the meta model can be transferred on Web and being readable by computers.
