Two Vector-Based Systems

I now focus on two vector-based systems, one that emphasizes term weighting, and the other term selection. The term weighting system was originally described by J. J. Rocchio in 1965 as part of the SMART system [39, ]. The term selection system was originally described by Donna Harman in 1988 as part of the IRX project [17, ].
