Counter-intuitive Cases of Data Fusion in Information Retrieval.
Ibraev, Ulukbek; Kantor, Paul; Ng, K. B.
Proceedings of the ASIST Annual Meeting, v38 p31-45 2001
Aspects of Data Fusion (DF) for information retrieval are explored. Based on a geometrical model of DF, it is shown that in the ideal case, performance of DF for a pair of information retrieval schemes may be approximated by a quadratic polynomial. Compares counter-intuitive cases of DF with cases that behave according to the geometric model. (AEF)
