Many pooling strategies have been developed for the pooling method. Herein, we address the question of identifying the best pooling strategy when evaluating systems using precision-oriented measures in presence of budget constraints on the number of documents to be evaluated. As a quality measurement we use the bias introduced by the pooling strategy, measured both in terms of Mean Absolute Error of the scores and in terms of ranking errors. Based on experiments on 15 test collections, we conclude that, for precision-oriented measures, the best strategies are based on Rank-Biased Precision (RBP). These results can inform collection builders because they suggest that, under fixed assessment budget constraints, RBP-based sampling produces less biased pools than other alternatives. date: 2016-09-12 date_type: published publisher: ACM official_url: https://doi.org/10.1145/2970398.2970429 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1588679 doi: 10.1145/2970398.2970429 isbn_13: 9781450344975 lyricists_name: Lipani, Aldo lyricists_id: ALIPA33 actors_name: Lipani, Aldo actors_id: ALIPA33 actors_role: owner full_text_status: public series: ACM International Conference on the Theory of Information Retrieval publication: ICTIR 2016 - Proceedings of the 2016 ACM International Conference on the Theory of Information Retrieval place_of_pub: New York, USA pagerange: 105-108 event_title: ICTIR '16: ACM SIGIR International Conference on the Theory of Information Retrieval, 12 - 16 September 2016, Newark, Delaware, USA book_title: ICTIR '16: Proceedings of the 2016 ACM International Conference on the Theory of Information Retrieval editors_name: Carterette, B editors_name: Fang, H editors_name: Lalmas, M editors_name: Nie, J-Y citation: Lipani, A; Zuccon, G; Lupu, M; Koopman, B; Hanbury, A; (2016) The impact of fixed-cost pooling strategies on test collection bias.
