摘要 

[目的]研究社交媒体知识协作网络中的明星节点和经纪人节点对知识传播的影响。[方法]运用Wikipedia中生物科学领域的197个知识点构建知识协作网络, 利用社会网络分析工具分析知识节点的相关指标, 并使用统计方法进行研究模型估计。[结果]处于网络中心位置的明星节点或拥有较多结构洞的经纪人节点, 其传播效果较好, 网络节点的粉丝群体协作规模在社交媒体知识传播中起到了半中介效应。[局限]样本局限于生物科学领域部分知识节点, 从整体网角度看, 界限选取和学科领域的不同是否会影响研究结果还有待进一步分析。[结论]明星节点和经纪人节点的优势一方面直接发挥作用, 另一方面通过粉丝群体的媒介效应发挥作用。

Abstract

[Objective] To study how the star role and broker role in social media knowledge collaboration network effect on knowledge dissemination. [Methods] This paper constructs knowledge collaboration network using 197 related biological knowledge samples from Wikipedia, analyzes the relevant indicators of knowledge nodes by social network analysis tools and studies model estimation using statistical methods. [Results] Star units in the network center position and broker units having more structural holes could get better dissemination effects. The scale of the node's fans group collaboration in the network plays a half intermediary role in social media knowledge dissemination. [Limitations] Samples are limited to the knowledge nodes in biological science field, and from the perspective of the overall network, whether boundary selection and discipline affect the study remains to be further analyzed. [Conclusions] The advantages of star nodes and broker nodes play a direct role on knowledge dissemination and an indirect role by the media effect of the fan group.

Key wordsSocial media knowledge collaboration network    Star nodes    Broker nodes    Fan group collaboration scale    Knowledge dissemination effect
