Data mining is being used throughout the world by many industries .To face the marketing competition,the marketing industry need to analyse the shopping basket of the customers to get their preferences,habits and their relationships. For this most of the industries use Apriori Algorithm,which was proposedby Agrawal,in 1993.Problem with Apriori is that all the items in the item set have same importance,but in real life it is better to have recommendations according to the relevant season,project and time. The solution was to divide the items or projects into categories and weights are given according to the no of items sold for each category. Then calculate the weighted support and confidence. © 2016,International Journal of Pharmacy and Technology. All rights reserved.
