一种基于XML的信息搜索技术

A XML-Based Approach for Information Search

以XML形式组织的数据结构层次清晰,语义明确。本文利用XML技术的这一特点,提出了一种基于XML的信息搜索方法:以用户需求信息的结构为基准,根据拓扑匹配原则,以倒向路径(L-R)的拓扑匹配为出发点,给出了信息搜索时有关用户需求在某一数据源中的匹配度Tmd计算方法。

Data or data sources organized in terms of XML have exact semantic descriptions and legible structures. In this paper, the authors propose a method for information search based on the XML technique. Considering the users＂ needs and the topological match, we study the inverse direction route（L-R） which stands for the leaf-root and propose a method to compute the topological match degree （Trod） when we search a need in a database.
