Abstract:
Recently, the volume of information retrieval from mobile phones and tablet PCs has been drastically increasing. With these search environments, traditional document-granular information retrieval is not the most appropriate methodology in terms of the screen size of the devices and communications traffic. XML element retrieval is one of the solutions for that, which is element-granular information retrieval and leverages both contents (text) and the document structure in order to extract only and all relevant descriptions from an XML document. In this seminar, I will provide an introduction to XML element retrieval, including my efforts on the Initiative for the Evaluation of XML Retrieval (INEX). I will also present a study on applying XML element retrieval technique into Web documents, through my participation to MobileClick at NII Testbeds and Community for Information access Research (NTCIR).
