The suggested measure possesses some interesting properties which make it useful in recommender systems and some other possible applications. In particular, it aggregates the bipolar information taking into account both the strength of the correlation and its sign. Simulta­neously, applied in collaborative filtering, it rewards strong association which is a desired property in making meaningful recommendations to a user.}, title={On Measuring Association between Groups of Rankings in Recommender Systems}, type={Text}, keywords={Association measures, Aggregation functions, Funkcje agregujące, Rating, Recommender system, System rekomendujący, Bipolarity, Dwubiegunowość, Collaborative filtering, Correlation coefficient, Współczynnik korelacji, Owa operator, Preference system, Ranks, Ordering, Porządkowanie danych, Miary asocjacji, System preferencji, Wspólna filtracja, Szeregi}, }
