摘　　要：[目的/意义]学术虚拟社区知识交流效率测度对于了解和改进学术虚拟社区本身有着积极的意义,也为相关知识交流效率评价方法提供了新的分析应用领域。[方法/过程]文章提出了一种利用博文作者网络进行学术虚拟社区知识交流效率测度的方法。通过汇总每位博文作者的浏览总量、推荐总数、评论总数、文章类别数量等特征设计了网络节点权值,并根据博文作者领域特征进行边权值设计。然后对该网络从路径长度、聚类系数等角度,分别按照学科版块和博文类别版块,结合时序演化特征,分析了相关版块中知识交流的效果和效率,并对相关现象和结论做了必要的总结。[结果/结论]对学术虚拟社区知识交流相关研究进行了较为完整的前期研究总结,并对需要关注的研究方向和内容作出了阐述和介绍。[Purpose/Significance]The measurement of knowledge exchange efficiency of academic virtual community has a positive significance for understanding and improving the academic virtual community itself,and also provides a new application analysis field for the evaluation methods of knowledge exchange efficiency.[Methods/Process]This paper proposes a method to measure the efficiency of knowledge exchange in academic virtual community by using networks of blog author.The network node weights are designed by summarizing the total number of views,recommendations,comments and blog category of each blog author.The edge weights in network are designed by the blog author's domain characteristics and blog category.According to the discipline section and blog category section,combining with the characteristics of temporal evolution,this paper analyzes the effect and efficiency of knowledge exchange in related sections from the perspective of path length and clustering coefficient,and makes a necessary summary of related phenomena and conclusions.[Results/Conclusion]It can provide a relatively complete pre-research summary for the research on knowledge exchange in academic virtual community,and elaborate and introduce the research direction and content that need attention.
