摘要

在Web上,普遍使用XML为文本集合提供轻量级语义。这种以文档为中心的XML集合需要一种能够优雅地处理结构约束和文档自由文本约束的查询语言。我们的主要贡献有三方面。首先,我们概述了为对所使用的XML结构有不同理解程度的用户量身定制的两个XPath片段,并给出了这些片段的语法和语义特征。其次,我们使用一个about函数扩展XPath,该函数具有基于文档组件与所表达的信息需求的相关性的最佳匹配语义。第三,我们使用INEX 2003测试套件评估结果查询语言,并表明在评估内容和结构查询时,最佳匹配方法优于精确匹配方法。

Best-match querying from document-centric XML
On the Web, there is a pervasive use of XML to give lightweight semantics to textual collections. Such document-centric XML collections require a query language that can gracefully handle structural constraints as well as constraints on the free text of the documents. Our main contributions are three-fold. First, we outline two fragments of XPath tailored to users that have varying degrees of understanding of the XML structure used, and give both syntactic and semantic characterizations of these fragments. Second, we extend XPath with an about function having a best-match semantics based on the relevance of the document component for the expressed information need. Third, we evaluate the resulting query language using the INEX 2003 test suite, and show that best-match approaches outperform exact-match approaches for evaluating content-and-structure queries.
