UPF at INEX 2011: Books and Social Search Track and Data-Centric Track

This article describes our participation at INEX 2011 in the Books and Social Search track and the Data-Centric track. In the Books and Social Search track we participated in the Social Search for Best Books task and studied the performance effects of using different query fields for query expansion. In the Data-Centric track we participated in the Adhoc task and the Faceted Search task. In the Adhoc task we studied the performance effects of using different indices depending on what type of object is asked for. For the Faceted task we used a fixed set of facets and experimented with the hierarchical and non-hierarchical presentation of them.
