Introduction Okapi at TRECs 2 and 3 During TRECs 2 and 3 ffl the new term-weighting functions were developed and refined as described in [1, Section 3.2] ffl a method of runtime passage determination and searching was devised [1, Section 4]; ffl an inefficient but surprisingly effective way of choosing routing terms was developed [1, Section 6]); ffl and a reasonably effective way of automatically expanding ad hoc queries with terms from documents retrieved in a pilot search was developed [1, Section 5]. TREC--4 City have submitted interactive runs in all the previous TRECs, with fairly undistinguished results.
