A New Recommendation Method for the User Clustering-Based Recommendation System

The aim of this paper is to create a new recommendation method that would evaluate the peculiarities of user groups, and to examine experimentally the efficiency of user clustering in order to improve the recommendations. To achieve this goal, we have analysed recommendation systems (RS), their components, operating principles and data, used for accuracy evaluation. The proposed method is based on user clustering; therefore, clustering-based RS are reviewed Finally, the proposed method is presented and tested with the most appropriate data set of all that discussed in the overview. The research has disclosed dependencies of the efficiency of recommendations on the number of clusters. The experimental results have shown that the proposed method can be applied to high density databases and the results of recommendations are better than those of traditional methods.
