Using Topic Shifts in XML Retrieval at INEX 2006

This paper describes the retrieval approaches used by Queen Mary, University of London in the INEX 2006 ad hoc track. In our participation, we mainly investigate element-specific smoothing method within the language modelling framework. We adjust the amount of smoothing required for each XML element depending on its number of topic shifts to provide a focused access to XML elements in the Wikipedia collection. We also investigate whether using non-uniform priors is beneficial for the ad hoc tasks.
