Abstract
Extensible Markup Language (XML) is used for not only describing structured documents but also for describing data just for generating XML from relational data. The former is called document-centric XML, and the latter is called data-centric XML. From studies on retrieving data-centric XML by using keyword searches, methods based on LCA have been proposed, while from studies on retrieving document-centric XML, methods based on information retrieval that focus on the granularity of XML elements have been proposed. However, documents generally have both data-centric and document-centric elements, so there are cases in which desired results cannot be returned by using existing research. We propose a method for constructing suitable search results for XML documents that include both data-centric and document-centric elements by considering a user’s query intention and element features (data-centric or document-centric). Our experiments show that both data-centric and document-centric elements need to be considered for actual XML documents.
