Abstract

XQuery and Keyword query are the main methods to get XML data. But the former is too complicated for non-professional users and the latter doesn't have enough semantic capabilities to capture user's intents completely. Based on data models, this paper analyzes the reasons which lead to the drawbacks of existing query methods. And then, a novel auto-navigating XML query model is proposed. The query model is composed of the XML data model, the query language and the query algorithm. The data model stores XML documents in a clustering way according to the semantic relativity. The query language has the intuitive grammars and is suitable for non-professional users to use. The query algorithm has auto-navigating capability and can find the target data from XML documents without complete structure information.
