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)

Kantor, Paul B.; Ng, Kwong Bor – Proceedings of the ASIS Annual Meeting, 1998
Categorizes different theoretical justifications of data fusion into two approaches, examines their implications, analyzes some unsuccessful data fusion experiments, and proposes two conditions for effective data fusion. Results indicate that the efficacy and inter-scheme dissimilarity are good predictors for effectiveness of data fusion.…
