Index Technology Oriented on XML Document Retrieval

How to retrieval and index XML documents is a hot research topic.This paper explores XML document index technology,including index structure design,and then gives a high effective XML index method.This method adopts distinct numbering scheme to establish index for XML document and DTD simultaneously,supporting retrieval both on context and structure effectively.It combines the thought of region based numbering scheme,inverted table and path index,using the DTD structure information to enhance the efficiency of query.Experiments indicate the method suggested in this paper can effectively reduce cost for creating indices of XML data and shorten the response time of query.
