To solve improve the performance of e-commerce recommendation system
considering four graph model of credibility based on the user-projects-property-label of timeliness is proposed
And this paper proposes also a new recommendation algorithm-Goods Recommendation Fusing Credibility and Timeliness-tag(CRFCT) for the model.The model algorithm using reliability model judges user type to improve the cold start of the new project.3 kinds of personalized prediction scoring methods are proposed based on rating information and the attributes of the project and user timeliness method
incorporating the three evaluation methods
by adjusting the parameters of alpha
beta
and gamma balance factor to determine the weights of influence factors of the three evaluation methods
so as to improve the accuracy of recommendation.Experimenting show that has higher accuracy and also has higher novelty
and to some extent effective to deal with the cold start problem of the new project recommendation compared with the traditional recommendation algorithm.
