Now, given each keyword (K) obtained from GlossEx, we recalculate its salience by considering the following three factors: 1) its original confidence value assigned by GlossEx (C GlossEx (K)); 2) the frequency of the keyword occurring in the aforementioned cue context (F cue (K)); and 3) the number of component words in the keyword (|K|).
we give more weight or incentive (I(K)) to keywords that are originally of high confidence, appear more frequently in cue contexts, and have multiple component words.
