Cоnsider the fоllоwing product review sаmple from Amаzon. “helpful” is а variable indicating the total number of “helpful” votes each review has received so far; “score” refers to the rating of the product being reviewed. Suppose your goal is to use the review text to train a model for predicting the sales of a product (which is highly correlated with its average rating on Amazon). (1) Which one of the two terms, “bake” or “great”, is more informative about review #4 in the review corpus? Justify your answer by calculating their TF-IDF scores. Note: The TF-IDF scores should be calculated after first word-stemming and then removing stopwords and non-words. Word-stemming replaces nouns in their plural form with their singular form and converts the past tense of a word to its present tense. Assume that stopwords = c(“is, “and”, “the”, “of”, “to”, “on”, “with”). Please specify your own list of non-words. (2) In this analysis, should we pre-process the review data by removing all the punctuation marks (e.g. paratheses and semicolons) from the text? Why or why not? Please explain.
