Abstract :
Ranking interestingness measure is a necessary part in the process of knowledge discovery from the extracted rules. Since the range of values of Interestingness measures are not unique, identifying a perfect measure is a challenging question to data mining community. Homogeneity of a measure always varies from 0 to 1; hence we ranked the measures by calculating the homogeneity coefficient, using the score of the respective measure on a set of rules. Also we introduced heuristic association measures, U Cost, S Cost, R Cost, T Combined Cost and ranked with existing measures using the ranking algorithm. Our measures are placed in better position on ranking, compared with the existing measures.
