摘要: [目的/意义]在社交网络中,意见领袖节点影响力对社交网络舆情的发展至关重要,构建全面科学的社交网络意见领袖节点影响力指数及计算分析模型可以更好地识别关键意见领袖,更好地监督和引导舆情走向。[方法/过程]基于信息论和p指数的相关理论,从社交网络中意见领袖受认可度、情感联系度和网络传播度3个维度构建意见领袖节点影响力OLEI指数算法,并提出社交网络中意见领袖节点影响力指数计算及分析模型。结合自然灾害"7·20"河南暴雨中典型舆情话题对所构建的OLEI指数算法进行验证和分析。[结果/结论]实证研究结果表明,OLEI指数中受认可度能够反映社交网络用户对其他用户产生的舆论影响程度和信任支持程度;情感联系度可以反映意见领袖节点引发社交网络较大的用户情感波动,意见领袖的网络传播度越大,其在社交媒体平台中的地位越关键。

Abstract: [Purpose/Significance] In social networks, opinion leader node influence plays an important role in the development of public opinion in social networks. Building a comprehensive scientific opinion leader node influence index and computational analysis model in social networks can better identify key opinion leaders and can better monitor and guide the direction of public opinion. [Method/Process] Based on the relevant theories of information theory and p-index, an OLEI index algorithm was constructed based on three dimensions of opinion leaders' recognition, emotional connection and network communication in social networks, and a model for calculating and analyzing the node influence index of opinion leaders in social networks was proposed. The OLEI index algorithm was validated and analyzed by combining the typical public opinion topics in the natural disaster "7·20" Henan rainstorm. [Result/Conclusion] The results of the empirical study show that the recognition degree in the OLEI index can reflect the degree of opinion influence and trust support of social network users on other users; the emotional connection degree can reflect that the opinion leader nodes have triggered greater user emotional fluctuations in the social network; the greater the network communication degree of the opinion leader, the more important the position it occupies in the social media network.

Key words: social networks, opinion leaders, node influence, index
