Abstract: User behaviour can be extracted from the web pages accessed by the end user while browsing the internet. This extracted behaviour helps in providing recommendations to the end user. This paper presents mining of frequent itemsets and refinement of usage clusters for web page recommendation. The not so interesting recommendations obtained from a cluster are in abundance due to large number of sessions in a cluster. To solve such a problem we intend to refine clusters on the basis of weighted frequent itemsets that in turn help to generate improved quality refined clusters. After getting refined clusters, the same can be used for a number of applications such as personalisation on the basis of interests of the end user, improvement in website structure and improving the accuracy of a recommender system. The accuracy of a centroid-based recommender system is evaluated using original and refined clusters.
