In this paper, we present a novel neighbourhood estimation method which is not only both memory and computation efficient but can also achieves better estimation accuracy than other cluster based neighbourhood formation techniques. In this paper we have successfully incorporated the proposed technique with a taxonomy based product recommender, and with the proposed neighbourhood formation technique both time efficiency and recommendation quality of the recommender are improved.
