Search and navigation in structured document retrieval: comparison of user behaviour in search on document passages and XML elements

This paper investigates search and browsing behaviour of users presented with two types
of structured document retrieval approaches: passage retrieval and XML element retrieval. Our findings, based on the system logs gathered from 82 participants of the INEX 2006 interactive track experiment (iTrack), indicate that XML element retrieval leads to increased task performance. In addition, qualitative analysis of our video study, where we recorded the interactions of four participants, highlights potential issues with the experimental design employed at iTrack 2006.
