Using the INEX Environment as a Test Bed for Various User Models for XML Retrieval

While in previous INEX workshops, XML retrieval tasks were divided roughly to CO (Content Only) and CAS (Content and Structure) tasks, the focus this year was to further refine those tasks so as to experiment with different user behaviors for viewing returned results. In particular interest is the new “Focussed” task that permits a single element along each path, thus solving the problem of XML result overlapping that we experimented in previous INEX workshops. In this paper we describe an algorithm for the new “Focussed” task as well as our algorithms and approaches for the other tasks.
