一种改进的知识社区中专家贡献度排名算法

摘要

A hot spot in recent studies of knowledge community is an expert calculated the size of the contribution of knowledge community.Based on knowledge community, through two indicators of activity of experts and popularity of experts, the factor of the knowledge contribution ability of the expert is introduced, the idea of traditional PageRank algorithm is used to improve a new influence ranking algorithm (Expert Contribution Rank).Finally,Compared through experiments with traditional algorithm to verify the validity of the algorithm.%近来研究的一个热点是知识社区中专家对知识社区的贡献度大小的计算方法。因此本文研究了知识社区中的专家对象，从专家的活跃度和专家的受欢迎度两个指标进行测度，在评价中引入专家的知识贡献能力因子，提出了一种基于传统的PageRank算法上的评价算法（expert contribution rank）模型，通过实验从算法的性能方面显示了排名算法的有效性。
