在P2P蓬勃发展的今天,人们从P2P文件交换系统中获得了不少的好处。然而Web服务因缺乏语义而不能更好地提供搜索服务,这一问题在P2P资源共享同样中存在,故难以简单地通过文本匹配的方法寻找到自己需要的资源。语义Web可以为Web服务提供灵活的查找方式,受语义Web的启发,提出一种基于标签和本体的P2P资源检索获取方法,并且讨论此方法在协作环境下的进化情况。
Today, when P2P is booming, people get a lot of benefits from P2P file exchange system. However, because of the lack of semantics, Web services can not provide better search services. This problem also exists in P2P resource sharing, so it is difficult to find the resources they need simply by text matching. Semantic Web can provide a flexible search for Web services. Inspired by the Semantic Web, a Web-based search and retrieval method based on tags and ontology is proposed, and the evolution of this method in a collaborative environment is discussed.
