The fuller name, Okapi BM25, includes the name of the first system to use it, which was the Okapi information retrieval system, implemented at London's City University[1] in the 1980s and 1990s

S-Class Information Retrieval The empirically validated retrieval progression is BM25 then learned-sparse then dense then hybrid fusion with re-ranking

In terms of Boolean algebra , the optimization of a complex Boolean expression is a process of finding a simpler one, which would upon evaluation ultimately produce the same results as the original one
