[Purpose/significance] This paper aims to construct a PROV provenance model and user credibility evaluation index for information dissemination process, quantify the credibility of information, and enrich and improve the method of credibility evaluation of socialized Q&A community platform.[Method/process] The paper analyzed the credibility of the data origination concept assessment information from the perspective of the information dissemination process, traced and recorded the source and dissemination of the information by establishing the relevant PROV data provenance model. The process, combined with the user credibility scores involved in the information dissemination process, was used to calculate the quantitative results of the credibility of the information.[Result/conclusion] Through the evaluation of the credibility of information, the information credibility evaluation method is further improved, which provides a new idea for optimizing the quality of community information.
