Weng, Li-Tung, Xu, Yue, Li, Yuefeng, & Nayak, Richi (2007) Efficient Neighbourhood Estimation for Recommenders with Large Datasets. In Twelfth Australasian Document Computing Symposium, Monday 10 December, 2007, Melbourne, Victoria.

Abstract

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.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
