Relevant Contextual Features in XML Retrieval


We present and analyze results of a collaborative user study carried out by the Interactive Track at INEX 2005. The overall goal of the Interactive Track is to investigate the behavior of users when interacting with components of XML documents. In this paper we use the data collected from this user study to investigate dependencies between several contextual features and the structural characteristics of the relevant components (e.g. type and number of relevant elements). The three contextual features analyzed are the user's familiarity with the topic, the type and specificity of the request, and the user's intention. The dependencies found indicate that XML retrieval systems should also benefit from the use of contextual information.
