基于RANK和结果缓存的XML关键字搜索引擎
发布时间：2019-04-10 15:05
【摘要】：XML已成为当前主流的数据存储方式,对其进行信息的提取尤为重要,主要方法有两个:1)用XPath,XQuery等工具,可对信息比较精确的提取,但用户需要知道其语法;2)对XML的关键字搜索(XKS),利用SLCA/ELCA等技术对结果进行剪枝,虽然可以很好地解决第一个问题,但可能误删结果。提出一种新的XKS方法,保留所有的查询结果,以网页的形式呈现给用户,缓存结果,根据用户对结果的反馈信息,利用RANK和排序机制对结果显示顺序做调整,达到查询的精确度要求。
[Abstract]:XML has become the current mainstream data storage mode, it is particularly important to extract the information. There are two main methods: 1) using XPath,XQuery and other tools, it can extract the information more accurately, but users need to know its syntax; 2) using SLCA/ELCA and other techniques to prune the results of the keyword search (XKS), of XML, although the first problem can be solved well, the result may be deleted by mistake. A new XKS method is proposed, which preserves all the query results, presents the results to the user in the form of a web page, caches the results, and adjusts the display order of the results by RANK and sorting mechanism according to the feedback information of the users to the results. Meet the accuracy requirements of the query.
