一种支持动态XML文档上关键字查询的索引结构
An Index Scheme for Keyword Search over Dynamic XML Document
摘要
Abstract
The index of XML document is important for its retrieval efficiency. The most of existing index schemes for keyword search consider static XML documents. But these indexes will face with widely re-label to increase the cost for database index maintenance when the XML documents are update frequently. In order to keep the index steady in dynamic environment,propose an index scheme DLSS (DDE Level Structure Summary) which applies to keyword search in dynamic XML document. The DLSS is based on an improved Dew-ey label which gives the new node with corresponding label when the document updates but not to justify the whole index scheme. The experimental results show that the DLSS index scheme not only keeps the index scheme steady in dynamic environment,but also realizes efficient for keyword search.关键词
