Qianbing Zheng · 2013
Along with the rise of social networking,users can interact,share information and cooperate online.However,that the expansion of information leads to the problem of reliability has received widespread attention.This paper proposed a combined trust model of CStrust based on text context information and user community structure,gave the confidence model framework,put forward the function of confidence by search engine,and designed a sorting algorithm based on degree of confidence.Experiment with Sina micro-blog data show that this algorithm is superior in reliability of Sina micro-blog default search algorithm,and can fully take into account the preferences of the user,the user's own influential factors,etc.,which is also superior to the traditional LDA algorithm.
