Question No. 2

You conduct a TFIDF analysis on 3 documents containing raw text and derive TFIDF ("data", document y) = 1.908. You know that the term "data'' only appears in document 2.

What is the TF of ''data" in document 2?

A2 based on the following reasoning:
TFIDF = TF1DF = 1 908
You then know that IDF will equal LOG (32)=0.954
Therefore, TFIDF=TF*0.954 = 1.908
TF will then round to 2

B4 based on the following reasoning:
TFIDF = TF1DF = 1.908
You then know that IDF will equal LOG (3/1 )=0.477
Therefore, TFIDF=TF'0 477 = 1.908
TF will then round to 4

C6 based on the following reasoning:
TFIDF = TF1DF = 1.908
You then know that IDF will equal 3/1=3
Therefore, TFIDF=TF/3 = 1.908
TF will then round to 6

D11 based on the following reasoning:
TFIDF = TF1DF = 1908
You then know that IDF will equal LOG(3/2)=0.176
Therefore, TFIDF=TF'0.176 = 1.908
TF will then round to 11
