A Unit of Retrieval Results for XML Documents
Kenji Hatano, Shunsuke Uemura · 2003
XML query languages adopt a SQL-style query to retrieve portions of XML documents. However, the query style of XML query languages is not suitable for XML document retrieval because it is di cult for users to specify both keywords and document structures of XML documents in order to retrieve portions of XML documents. In this paper, we propose a method for defining a unit of retrieval results to develop a keyword-based XML document retrieval system. Using our method, we can reduce the number of targeted retrieval results for XML documents, so that we can speed up retrieving retrieval results and enhance overall performance of XML document retrieval system.
