Research and Implementation of Index for XML Documents in Dynamic Environment
基于XML的索引动态更新研究与实现

Proposes an inverted index structure that supports dynamic update, including both structure and content updates. In the proposed index structure, term and element tag based on inverted list, in addition to a horizontal term-based index, a vertical index based on GID of element identifier is added. The dual index structure supports fast and efficient updates on the parts of a document. The method of implementation by using RDBMS and Co-occurrence skill in semantic retrieval have been proposed.
