Design and Analysis of Efficient Collaborative Filtering Based Optimization Approach
Main Article Content
Abstract
The large amount of information that is currently being collected (the so-called “big dataâ€), have resulted in model-based Collaborative Filtering (CF) methods to encountering limitations, e.g., the sparsity problem and the scalability problem. It is difficult for model-based CF methods to address the scalability-performance trade-off. Therefore, we propose a scalable clustering-based CF method in this paper that can help provide a balance by re-locating elements in the cluster model. The rapid development of information technology takes our shopping into the orbit of information. With the network construction of resources, the amount of shopping resources increases rapidly. Collaborative filtering (CF) is a technique commonly used to build personalized recommendations on the Web. Some popular websites that make use of the collaborative filtering technology include Amazon, Netflix, iTunes, IMDB. The most important issue which influences the collaborative filtering recommendation accuracy is the so-called data sparseness. Data sparseness causes the system difficulty in determining the nearest neighbors of the target user accurately. Clustering can solve this problem to some extent. Grouping a set of physical or abstract objects into classes of similar objects, this process is called as clustering. This paper presents the methods to generate recommendations using clustering-based collaborative filtering approach.
