It has been observed from time to time that DF applied to a pair of systems or schemes for IR may yield results that are better than those of either participating scheme. It has been conjectured that this occurs only rarely, or occurs only when poor schemes are being combined, or occurs only for problems in which there are so few relevant documents that the results are probably due to statistical fluctuation. Based on a geometrical model of DF, we derive an equation for effective DF. This equation shows that in the ideal case the performance of a pair of IR schemes may be aproximated by a quadratic polynomial. We statistically test this assumption for TREC5 Routing data. Results of the regression analysis shows that our equation for the effect of DF is generally valid.<\/jats:p>","DOI":"10.1002\/meet.1450390114","type":"journal-article","created":{"date-parts":[[2005,1,31]],"date-time":"2005-01-31T10:50:43Z","timestamp":1107168643000},"page":"124-129","source":"Crossref","is-referenced-by-count":4,"title":["Exploration of a geometric model of data fusion"],"prefix":"10.1002","volume":"39","author":[{"given":"Ulukbek","family":"Ibraev","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwong Bor","family":"Ng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul B.","family":"Kantor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,31]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"crossref","unstructured":"Bartell B.
