Ibraev, Ulukbek; Ng, Kwong Bor; Kantor, Paul B. – Proceedings of the ASIST Annual Meeting, 2002
Explores aspects of data fusion (DF) for information retrieval (IR) using a set of data from the Fifth International Conference on Text Retrieval (TREC5). Derives an equation for effective DF based on a geometric model and shows that the performance of a pair of IR schemes may be approximated by a quadratic polynomial. (Author/LRW)
