Description:

Staff are the people who are involved in the creation of the game.

Datatype:

set with elements

Possible Values:

{"", etc.}

Similarity Calculation:

|Fi(A) ∩ Fi(B)| is the number of staff members involved in both games A and B.

|Fi(A) U Fi(B)| is the number of staff members involved in games A and B.

                   |Fi(A) ∩ Fi(B)|

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

                    |Fi(A) U Fi(B)|

example:         game A = "The Binding of Isaac (Windows)", Fi(A) = ("Danny Baranowsky", "David Tyler", "Edmund McMillen", "Florian Himsl", "Jordan Fehr", "Matthias Bossi")

                      game B = "Grey Matter (Windows)", Fi(B) = ("Danny Baranowsky", "Edmund McMillen", "Tommy Refenes")

              |Fi(A) ∩ Fi(B)| = |("Danny Baranowsky", "Edmund McMillen")| = 1

              |Fi(A) U Fi(B)| = |("Danny Baranowsky", "David Tyler", "Edmund McMillen", "Florian Himsl", "Jordan Fehr", "Matthias Bossi", "Tommy Refenes")| = 7

                   Simi(A, B) = (2 / 7) * 100 = 28
