Zipf’s law expresses the proportion of term-occurrences associated with a term as a function of the term’s frequency-based rank. zipf’s law can be stated as follows: pt = c , rt where pt is the proportion of term occurrences associated with term t, rt is the frequency- based rank associated with term t, and c is a constant (for english, c = 0.1). what proportion of term-occurrences would be removed from the collection if we ignored all occurrences of the five most frequent terms in the collection?
