Idf factoring
Webto substitute idf factor during weighting terms. Their thorough experiments did not exhi-bit a uniform superiority with respect to standard tf.idf [3]. Supervised term weighting schemes, however, seem more reasonable than unsupervised ones for TC task. Recently, Liu et al. [13] proposed a probability based supervised term weighting WebIDF is close to zero for a term that occurs in almost all documents and large if it occurs in just a few documents. The weight of a term, w, or the TFxIDF equation, then takes this form: w = tf (f) * df (n) In table II the n-value column is changed to df (n) (log (N/n)) and the f-values in the body replaced by w.
