- Abstract
Under the circumstance of the big data, because of the low efficiency and low performance of analysis and calculation in stand-alone mode, the traditional recommendation algorithm is limited greatly, recommended time and recommended precision is difficult to guarantee. This thesis makes a improvement on the user-based collaborative filtering algorithm. The user similarity calculation is based on the normalized method, which makes user rating more reasonable and reduces the data sparse. Meanwhile the algorithm can be run on the massive clusters, which improve the operation efficiency of the system and the scalability of the system significantly. Finally, designing the scheme of recommendation system experiments and the experimental results show that the accuracy of the improved algorithm is superior to the traditional collaborative filtering algorithm and strengthen the efficiency at the same time.
