Abstract

Best match systems in Information Retrieval have long been one of the most predominant models used in both research and practice. It is argued that the effectiveness of these types of systems for the ad hoc task in IR, has plateaued. In this short paper, we conduct experiments to find the upper limits of performance of these systems from three different perspectives. Our results on TREC data show that there is much room for improvement in terms of term-weighting and query reformulation in the ad hoc task given an entire information need.
