社会网络视域下的艾滋病传播路径与预防机制研究——基于知乎问答的经验分析

Research on HIV Transmission Path and Prevention Mechanism under the Perspective of Social Network:Based on Empirical Analysis of Zhihu Questions and Answers

基于社会网络理论,采用Bambina社会支持编码对以艾滋病为关键词的知乎问答爬虫数据进行分类并进行卡方检验;然后利用NETDRAW和UCINET软件对爬虫数据的中心性以及艾滋病传播与预防机制的影响进行检验。研究发现:(1)知乎问答网络中用户的地位不平等,网络结构不合理,权力和信息分散。(2)社会支持关系网由4~6名核心用户组成,起着支撑作用。大部分用户处于边缘位置,仅接受而不提供信息,并且用户地位不平等。(3)总体来看,用户参与度越高,获得的社会支持种类也越多,但大多数用户处于边缘地位的现状对社会网络密度产生了负向的影响。

Based on the social network theory,the Bambina Social Support Code was used to classify the Q&A reptile data with AIDS as the key word and perform chi-square test. Then use Netdraw and Ucinet software to test the impact of the centrality of reptile data on AIDS transmission and prevention mechanisms. Research conclusions :(1)Users in the Q&A network are not equal in status,the network structure is unreasonable,and power and information are scattered.(2)The social support network consists of 4-6 core users and plays a supporting role. Most users are at the edge, only accepting without providing information,and the user status is unequal.(3)Overall,the higher the user engagement,the more types of social support are obtained,but the current status of most users has a negative impact on the density of social networks.
