| 摘 要： | 针对XML文档索引查询中非法路径查询响应时问过长的问题，提出一种利用DTD模式进行预处理的索引方法。建立索引DWBI，采用新的基十区域编码方式，有效地支持祖先一后代判断。查询时利用DTD模式对查询进行预处理，再查询带有DTD信息的XML索引树，从而提高查询的效率。

| Abstract: | Aiming at the problem that the response time of illegal path query is too long, this paper proposes a new indexing method which proceeds pretreatment with DTD schema of XML document.The new index DTD and WAN-Based Indexing(DWBI) adopts a new region-based numbering scheme which can determine the ancestors-descendant relationship between a pair of objects effectively.It uses the DTD to pretreat the querying and queries XML index tree which has been appended DTD information, so that the efficiency of the query... |
