Datatype:

set with elements

Possible Values:

{"Action", "Adventure", "Strategy", etc.}

Similarity Calculation:

  |Fi(A) ∩ Fi(B)| is the number of distinct elements shared by both games A and B

  |Fi(A) U Fi(B)| is the number of distinct elements of games A and B

                      |Fi(A) ∩ Fi(B)|

  Simi(A, B) = --------------------- * 100

                       |Fi(A) U Fi(B)|

   example:         game A = "Shining Force (SEGA Genesis)", Fi(A) = ("Role Playing (RPG)", "Strategy")

                         game B = "Beyond Oasis (SEGA Genesis)", Fi(B) = ("Action", "Role Playing (RPG)")

                 |Fi(A) ∩ Fi(B)| = |("Role Playing (RPG)")| = 1

                 |Fi(A) U Fi(B)| = |("Action", "Role Playing (RPG)", "Strategy")| = 3

                     Simi(A, B) = (1 / 3) * 100 = 33
