Calculation of Weights for Individual Attributes
• Number of Common Friends:
Rule: If the number of common friends is more than 15% of the total number
of friends (Common Friends Ratio CFR), then the PR score is maximum for the
two people. The minimum of the PR score of the two individuals is taken as the
common PR score. If the number of common friends to the total number of
friends is between 0 to 15 percent then the PR score is adjusted between 0 to 10.
I.e.
if
CFR >= 15then PR score = 10
else
PR score = CFR / 1.5
Calculating Weights Dynamically :
Eqn 1: The addition of all the weights is 1
Eqn 2: W1 is X% more than w2
Eqn 3: w2 is Y% more than w3
Computing the final Proximity Score:
