Input: | Tokenization allows identifying significant keywords for the IR, which allows counting and obtaining their frequency |
Output: | Tokenization = 1 allows = 2, identifying = 1, significant = 1 keywords = 1, for = 1 the = 1, IR = 1, which = 1 counting = 1 and = 1 obtaining = 1 their = 1 frequency = 1 |
