Question 21

+4 marksNumerical answer

A TF-IDF model is applied to a document corpus of 50,000 documents. The term "optimization" appears in 750 documents. In a specific document, "optimization" appears 8 times, and the total number of words in that document is 1200. Using log base 10 ( log10), compute the TF-IDF score for "optimization" in this document. Enter your answer correct to three decimal places.
