Efficient Neighbourhood Estimation for Recommenders with Large Datasets
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.
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.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
