摘要 通过分析XML的数据特点以及一些已有的系统,提出一个带反馈的系统,充分利用XML文档的结构信息,帮助用户构建“相关的”、“感兴趣”的查询式,以便进一步的查询能有较高的准确率.具体的工作是建立路径关键词的倒排索引,在界面方面作一些扩充,提高检索系统的易用性.同时提出进一步的工作:在文档类型未知的情况下,通过聚类,为用户提供大概的分类,指导用户进行信息搜索. A feedback system is designed by using the data functions of XML to help users construct "relevant" and"meaningful" queries for higher accuracy. Work involves the establishment of inverted index for path-term, and the easy-to-use interface expansion which raises the usability of existing retrieval system. Further work is suggested through assembling techniques to give general information of classification when XML document is unknown.
