| 摘 要： | 随着XML的日益流行 ,基于XML的全文检索应用需求也迅速扩大。在这些应用中 ,native XML数据库是发展方向。虽然商业化的native XML数据库已经出现 ,但其全文检索的性能还不尽人意。本文提出一种方法 :在传统的倒排索引的框架下 ,对XML的标记建立索引 ,使得一个全文数据库能够以Native的方式存储、索引、检索和输出XML文档 ,成为一个真正意义上的native XML全文数据库 ,既有传统全文数据库的优越性能 ,又能满足基于na tive XML的应用需求

| Abstract: | The requirments of applications based on XML get more and more abroad along with that the XML is increasingly popular. In these applications, the native XML database is the direction of development. Although the commercial databases based on native XML had come forth, their performance in full text retrieval did not match expectation of customers yet. In this paper, we realize a method, which can build index of XML tags in the structure framework of traditional inverted index, and enable a full text database to store, search and output XML documents with native format as a native XML database. Such a database not only has the eximious performance of full text database but also can execute the applications based on native XML. |
