本体在Web服务发现中的应用

现在人们主要通过UDDI来查找Web服务,但其仅仅基于关键字,这决定了它不能根据所需功能的语义来更好地发现Web服务。本文先试图用DAML-S语言来描述Web服务的功能本体,然后提出了一个Web服务匹配框架-DAML-S/UDDI匹配器框架（DUMF）。虽然这一框架本身存在一些不完善的地方,但随着进一步改进,预计将在一定程度上解决Web服务发现的问题。

Apply Ontology when discovering Web Services

Now people mostly discovery web services by UDDI,but its depending on key words decides that we can not better find by the semantic of the function needed.This paper first tries to describe the function ontology of web services by using DAML-S language,then gives a framework of web services matching-DAML-S/UDDI matchmaker framework – DUMF.There still exist some imperfect places in it,but with the ceaseless improvement,we wish it can solve the problem in a certain extent.
