CSE494 HW1 Question 2 clarification

[Sree <slakshmi@asu.edu>]

Some of you lost points in HW1 for question 2 in Vector space model for  
wrongly calculating the term weights:

Here is the formula given to you:

                              [TFik * log(N/nk)]
         Wik =          _______________

                             [sum [(TFik)^2 (log(n/nk))^2]]^1/2


Given 2 terms,"information" and "retrieval" term weights  for ducument i 
would be:

                    [TFi1 * log(N/n1)]
 Wi1=         _______________

              [(TFi1)^2  (log(n/n1))^2 + (TFi2)^2  (log(n/n2))^2]^1/2

and

                            [TFi1 * log(N/n2)]
 Wi2=               _______________

              [(TFi1)^2  (log(n/n1))^2 + (TFi2)^2  (log(n/n2))^2]^1/2

Those who miscalculated lost points. If you have questions reagrding
