摘 要:[目的/意义]健康超话中存在基于规则设定的形式意见领袖和发挥实际作用的真正意见领袖。甄别健康超话中真正的意见领袖并分析其对不同类型用户参与行为的引导作用,有助于健康超话的管理和发展。[方法/过程]首先,基于用户活跃度、话题相关性和网络位置三个属性构建三层次意见领袖甄别模型;其次,通过量化计算意见领袖影响力,分析健康超话中意见领袖的引导作用;最后,以“系统性红斑狼疮”健康超话为例进行实证研究。[结果/结论]三层次模型能够筛选出健康超话中实际的意见领袖,其甄别效果优于单一属性的识别方法。意见领袖对健康超话中的信息传播呈现正面引导作用,对不同参与类型的用户以及用户的不同参与行为均有影响。[Purpose/Significance]There are formal opinion leaders based on rule setting and real opinion leaders who play a practical role in health super topic.It is helpful for the management and development of health super topic to identify the real opinion leaders and analyze their guiding on different types of users'participation behaviors.[Method/Process]Firstly,a three-level opinion leader identify model was constructed from three attributes of user activity,topic relevance and network location.Secondly,the influence of opinion leaders was quantified to analyze the guiding effect of opinion leaders in healthy super topic.Finally,taking"systemic lupus erythematosus(sle)"healthy topic as an example was for empirical study.[Result/Conclusion]The three-level model can filter out the actual opinion leaders in the health super topic and its identify effect is better than that of the single attribute identification method.Opinion leaders have a positive guiding effect on the information dissemination in health super topic,and have an impact on users of different participation types and their different participation behaviors.
