Document frequency is

A. query and document

B. query only

C. term only

D. term and document

E. term, query, and document

Expert Solution

Its D) term and document

Its number of documents in which term appears. So its a function of term and document

eg.

d1: word1, word2, Word3

d2: word2

d3: word1

document Frequency of word2 is 2 as it appears in 2 documents
