This question is on IR. Consider the Vector Space IR system discussed in lectures. For this question we use the following weighing scheme. If d is a document and t is a term, then N weight(t, d)= TFid log10 If q is a query and t is a term weight(t. q) is similarly defined. Recall that given a query q and a document d. v(q)-v(d) score (q, d)= || (q)|||v(d)|| Consider a document D in which the word hash appears 10 times, table appears 3 times and has 10 other distinct words. Let D be a document in which the word hash appears 10 times and the word table appears 2 times. When the query is hash table which document is more relevant? Assume that df, all the terms from D and D is N/10. Explain your answer. (20 Points)
