Feedback algorithm of XML retrieval on element level
Shan Wang · Computer Engineering and Applications Journal · 2010
As the de-facto standard for data representation and exchange on the Web,XML is being widely used in many applications.Recent trends in IR research demonstrate the growing interest in XML retrieval on element level.Many open issues appear when considering the effectiveness of XML retrieval on element.A new feedback algorithm is implemented in LEMUR system to improve the effectiveness of XML retrieval on element.The performance of the new feedback algorithm is satisfactory.The data of the long-term experiment is provided by INEX.Experimental results demonstrate that the precision of retrieval results on element level is increased 15.70% when adding content information only and 18.19% when adding both content and structure information.
