Abstract:

This paper describes the work carried out by DERI for the Enterprise Search track at TREC 2008. We participated in both the expert search task and document search task of the track. For both tasks we made use of novel learned term-weighting schemes. For the expert search task, we used two different approaches namely a profiling approach and a two-stage document centric approach. We found that the document centric approach outperforms the profiling approach on previous years TREC data. For the document search task we adopted a standard retrieval framework and made use of the learned term-weighting schemes previously developed for the ad hoc retrieval task.
