摘要
万维网上大量的异构、非结构化的数据使人们难以有效地发现自己所需的信息 .作为网上通用的元数据描述工具 ,语义Web中的RDF(S)可以对网上信息建立规范化表述 。
The large amount of unstructured, heterogeneous data resource on the world wide web makes difficult for users to seek the information that satisfy their need. As the generic meta data description language in semantic web,RDF(S) can help to formally express information resource contained in a web site. The formal model of retrieval system combined with vertical web sites can improve efficiency of information retrieval.
