基于Web具有的一些特征和应用于语义Web的知识表示语言RDF,分析了RDF提供的语法基础即如何用XML来实现语法,以及RDF如何无二义性地描述资源对象的问题,使得描述的资源的元数据信息成为机器可以理解的信息。在此基础上,提出了一种新的适合Web发展需要的知识表示方法,为智能应用领域提供基础;并阐述了以RDF为基础的知识表示语言可较好地实现语义Web的知识表示。最后通过基于OWL知识表示实例的语义检索应用给予了说明。
On the base of current knowledge representation language RDF and the features of Web, this paper analyzes the phraseological foundation of RDF which RDF realizes syntax with XML, and how RDF describe resource objects to make metadata become understandable informa- tion for machine. Then it gives a new method of knowledge representation used in Web that can be the base of intelligent application field of Web, and demonstrates knowledge representation language based on RDF which can better realize knowledge representation on the Semantic Web. It is explained by applying an example of knowledge representation based on OWL to semantic search finally.
