Study on Collaborative Filtering Algorithm of Fusion Context-Aware Calculation

Abstract

In this paper, the project of context awareness information is introduced into the traditional collaborative filtering algorithm based on item, modeling by context awareness, put forward a kind of combination of context-aware computing collaborative filtering algorithm. The algorithm of the project context similarity calculation of similar fusion to the project, and then preference prediction and recommend using collaborative filtering algorithm, test the indicators of algorithm optimization, efficiency and accuracy of the proposed algorithm.
