- Abstract:

It’s an excessively informational and more fragmented era that is contributed to the development of information technology and the Internet. At present, personalized recommendation is a relatively effective way to help users gain various network information. Recommendations may not be ideal as the traditional algorithms rarely focus on the fast speed of information updating and change of users interests. We propose a combined recommendation algorithm by introducing an interception factor and calls it the CR algorithm. The core idea of it is to introduce the interception factor to the content-based recommendation algorithm and user-based collaborative filtering algorithm. The mixed recommendation consists of the content-based recommendation algorithm and user-based collaborative filtering algorithm. Recommending results of CR algorithm are divided into the outcomes produced by mixed recommendation algorithm and the user-based collaborative filtering algorithm. It is the publishing time of information that decides which algorithm should be chosen to produce recommendations: the mixed recommendation algorithm is selected when the difference between browsing time and message publishing time does not exceed some threshold, or directly chooses the user-based collaborative filtering. Simulation results based on real data show the algorithm we proposed is superior to other existing algorithms.
