Abstract

In this paper, we describe University of Otago's participation in Ad Hoc, Link-the-Wiki Tracks, Efficiency and Data Centric Tracks of INEX 2010. In the Link-the-Wiki Track, we show that the simpler relevance summation method works better for producing Best Entry Points (BEP). In the Ad Hoc Track, we discusses the effect of various stemming algorithms. In the Efficiency Track, we compare three query pruning algorithms and discusses other efficiency related issues. Finally in the Data Centric Track, we compare the BM25 and Divergence ranking functions.
