The report was hosted by Professor Yan Zhijun. A number of teachers and students from the School attended the report.

　　The report focused on Continuous Knowledge Contributors. The continuous knowledge contribution of community members in social media is mainly affected by five factors: the number of user reviews, the average score of receiving help comments, the average score of giving help comments, the ratio of negative evaluation and the total number, and the number of community members to be trusted. The study collected data from Epinions.com website to test the hypothesis, and finally found that the five factors have significant impact on the continuous knowledge contribution. The study results have theoritical and practical significance in the knowledge sharing research field.
