摘　　要：参照都柏林核心元数据规范构建网页信息的标引框架,提取网页特征信息,采用ADO技术实现网页信息的自动标引,实验结果表明,标引信息映射到网页的正确率为100%。最后,将标引技术应用到互补结构网络智能代理终端,验证UCL标引方法的有效性。实验结果显示,通过基于UCL的网页信息自动分类及标引技术能够实现信息的主动服务,满足用户的个性化需求。Indexing frame of Web page information is constructed referring to Dublin core metadata. Web page＇ s characteristic information is extracted. Web page information autoindexing is realized by using ADO technology. The experiment result indicates that the accurate rate of mapping indexing information to Web page reaches 100%. Finally, classification and indexing technology are applied to the intelligent agent termination of the complementary architecture network. The effectiveness of UCL indexing method is proved. The experiment result indicates that through Web page information auto - classification and auto - indexing technology based on the UCL, active service of information is realized and user＇ s individual demand is satisfied
