Description:

Datatype:

set with elements

Possible Values:

{"Foreign Language", "Geography", "Science", etc.}

Similarity Calculation:

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

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

                   |Fi(A) ∩ Fi(B)|

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

                    |Fi(A) U Fi(B)|

 

example:         game A = "Where in the World Is Carmen Sandiego? (SEGA Genesis)", Fi(A) = ("Geography")

                      game B = "The Oregon Trail (DOS)", Fi(B) = ("Geography", "History")

              |Fi(A) ∩ Fi(B)| = |("Geography")| = 1

              |Fi(A) U Fi(B)| = |("Geography", "History")| = 2

                   Simi(A, B) = (1 / 2) * 100 = 50
