Cognitive Maps Historical Approach Introduced in 1970s for representing social scientific knowledge. Signed digraphs where a positive link from vertex A to vertex B indicates that A causally increases B, whereas a negative link from A to B means that should A happen, the chances of B happening are reduced. Indirect Effect of A on B over the path pi is negative if the number of negative signs (of the edges) is odd, and positive otherwise. Total Effect of A on B would then be derived from the indirect effects over all possible paths: the total effect of A on B is negative if all the indirect effects are negative, is positive if all the indirect effects are positive, and indeterminate otherwise. © ABB Group March 3, 2011 | Slide 10
Cognitive Maps Weighted Approach Alternative Solution: creating a weighted digraph removes the uncertainty related to the sign calculations requires higher level of granularity in defining the dependencies of causes on one another w AB p = wA , j × w j , j × L w j , B , × i 1 1 2 w AB wAB, p = ∑ i i n © ABB Group March 3, 2011 | Slide 11
