Setup: (Sаme exаct setup аs in the previоus questiоn.) Suppоse you have a set of 100,000 documents about sports. You intend to use the standard “bag-of-words” representation of these documents for your data mining tasks. One of the most popular schemes for calculating the importance of different words within a document is TFIDF. Let’s assume that you are looking at some specific document Doc1 and are trying to calculate TFIDF scores for two keywords that appear in this document, i.e., keyword pitcher and keyword batter. Answer the following question. Question: Assume that keywords pitcher and batter appear in the same number of documents (among the possible 100,000). However, within document Doc1, keyword pitcher appears more times than keyword batter. Which of the following is true about the TFIDF scores that keywords pitcher and batter will be assigned for document Doc1?
