This applied weight to a 2-D recommendation space which is evaluated by the recommender system operated in conventional web environment for recommendation, making recommendation considering multidimensional elements possible. MAEs on five experimental data were compared. The NBCFA which adopted product quality as weight revealed high recommendation accuracy. When popularity weight is used, NBCFA and CMA reveal 1.4% and 4.3% respectively in performance improvement.
