In this paper we introduce a novel approach for query performance prediction based on ranking list scores dispersion. Starting from the premise that different score distributions appear for good and poor performance queries, we introduce a set of measures that capture these differences between both types of distributions. The proposed measures will employ the ranking list, output of a search system, as an information source to predict query performance in terms of MAP. The obtained results reveal a significant correlation degree with MAP and are very similar to those achievedwithmore complexmethods. Finally some generic open questions that could guide further research on query prediction methods are introduced.
