Jiguang Zhao · 2011
This paper proposes a recent-biased trust model(RBTM) based on time series,and the existed P2P model is the basis of RBTM.It applies time series vari-segment dimension reduction to evaluate time unit(ETU) and brings in a more reasonable time degenerating factor,also gives a detailed description to the addition of a new data.According to the historical time information of nodes transaction,it can adaptively update the recommendation trust based on content similarity and value of feedback evaluation.Experimental results demonstrate that the trust model has better scalability and lower operating expenses.
