Requirements: Consider the term-document count matrix for a collection of 10 documents and do the following. (2 points each) Q1) Calculate the IDF vector for the terms above. Q2) Calculate the TF-IDF vectors for documents 1 to 7. Q3) Using the values in Q2, calculate the L2 norm for documents 1 to 7. Q4) Using the answers of Q2 and Q3, compute the cosine similarity score between Doc1 and documents 2 to 7. (i.e. cos(Doc1, Doc2), cos(Doc1, Doc3) , cos(Doc1, Doc4), .., cos(Doc1, Doc7)). Q5) Rank the documents (2-7) according to the similarity with Doc1; from the most similar to the least similar
