摘要
【目的】对新媒体环境下社会公益舆情网络结构特征和信息传播展开研究,对相关部门加强社会公益网络舆情监管,为充分利用新媒体平台开展社会公益服务提供帮助。【方法】基于社会网络分析法,以新浪微博"画出生命线"话题数据为样本,从中心性、聚类和K-核三个社会网络指标出发,对新媒体环境下社会公益舆情网络结构特征和信息传播展开研究。【结果】实证研究结果表明,新媒体环境下的社会公益舆情网络为无标度网络,各子社区具有相似的网络结构,核心网络虽相对紧密但分布广泛,社会公益网络舆情已经进入移动时代。【局限】数据来源不够广泛、未剔除沉睡用户数据可能导致的研究偏差。【结论】在理论层面为社会公益网络舆情提供新的研究视角,在实践层面对相关部门加强舆情监控具有指导作用。
[Objective] The paper aims to help the government administrate online public opinion and social media profiles more effectively. [Methods] First, we retrieved data on the topic of ＂Draw up the Lifeline＂ from Sina Weibo. Then, we used centrality, cluster and K-core indicators to analyze the network structure and dissemination patterns of public opinion with new media. [Results] We found that online public opinion is disseminated through a scale-free network, and all communities had similar structures. The core network was relatively close but widely distributed, and the mobile technology played some major roles. [Limitations] The collected data was not comprehensive and the inactive users were not removed, which might generate some biased results. [Conclusions] This paper provides some new perspectives to research on social welfare movements. It also lists some practical guides to regulate online public opinion.
