区块链环境下社交网络用户意见领袖识别与影响力研究

Research on Recognition and Influence of Social Network User Opinion Leaders in Blockchain Environment

[目的/意义]对区块链环境下的社交网络用户意见领袖进行识别,分析意见领袖影响力和特征,有助于更好地了解区块链环境下社交网络的信息传播特征,从而为其他社交网络平台利用区块链技术进行更好地建设。[方法/过程]基于区块链和社交网络中意见领袖的相关理论,从中心性和受认可度两个维度出发,建立区块链环境下的社交网络意见领袖评价指标体系,构建区块链环境下社交网络意见领袖识别模型,并建立意见领袖影响力评价指标,应用层次分析法确定指标权重。[结果/结论]以网络爬虫方式获取区块链社交平台Steemit的数据,实验数据分析结果表明本文构建的区块链环境下的社交网络意见领袖识别模型和评价指标,具有一定的实用性。

[Purpose/significance] Recognizing the opinion leaders of social network users in blockchain environment and analyzing the influence and characteristics of opinion leaders will help to better understand the information dissemination characteristics of social networks in blockchain environment, so as to better construct other social network platforms by using blockchain technology.[Method/process] Based on block chain theory and the relevant theories of opinion leaders in social networks, we construct a social network opinion leader evaluation index system in blockchain environment from the two dimensions of centrality and recognition, construct social network opinions in blockchain environment leader identification model, establish the influence evaluation index of opinion leader and determine the weights of each index through the method of the analytic hierarchy process.[Result/conclusion] The data of the blockchain social platform Steemit is obtained by web crawling, the experimental data analysis results show that the social network opinion leader identification model and evaluation indicators constructed in blockchain environment in this paper have a certain practicality.
