Abstract

Abstract: As an international standard of data exchange，XML has been run through the Internet application in various fields. Temporal information as XML attribute plays an important role.This paper presents a new temporal XML indexing method，which based on XPath expansion of the model.This paper also constructs node table and semantic temporal tree，and divides node set in accordance with the time of the semantic point.New index method efficiently processes queries in temporal XML.

Key words: semantic, Extensible Markup Language（XML）, XPath

摘要： XML作为一种数据交换的国际标准，已经贯穿于Internet应用的各个领域之中，时态作为XML信息的属性发挥着重要的作用。基于对XPath扩展后的模型，提出一种新的时态XML的索引方法，建立结点表，构建语义时态数据树，并根据各语义点的时间段对结点进行点集划分。新的索引方法提高了对时态XML文档查询效率。
