Calculating the dissimilarity between term frequency vectors
WebTerm frequency-inverse document frequency weights. In the classic vector space model proposed by Salton, Wong and Yang the term-specific weights in the document vectors are products of local and global parameters. The model is known as term frequency-inverse document frequency model. The ... 1. The tf–idf is the product of two statistics, term frequency and inverse document frequency. There are various ways for determining the exact values of both statistics. 2.
