虽然网络社区是各种社会活动的重要平台，但许多网络社区无法生存，这促使研究人员调查影响网络社区成长和生存的因素。我们全面研究了各种社交网络功能对Reddit社区的增长和生存的影响。我们发现，几个社会网络的功能，包括集团比，密度，聚类系数，互惠性和集中化，社区的生存有显着的影响。与此相反，我们还表明，本文研究的社会网络功能只有微弱的影响社区的增长。此外，我们进行了实验，预测未来的增长和生存的在线社区的社交网络功能。结果表明，社会网络特征是有用的预测社区的生存，但不能预测他们的成长。
While online communities are important platforms for various social activities, many online communities fail to survive, which motivates researchers to investigate factors affecting the growth and survival of online communities. We comprehensively examine the effects of a wide variety of social network features on the growth and survival of communities in Reddit. We show that several social network features, including clique ratio, density, clustering coefficient, reciprocity and centralization, have significant effects on the survival of communities. In contrast, we also show that social network features examined in this paper only have weak effects on the growth of communities. Moreover, we conducted experiments predicting future growth and survival of online communities from social network features. The results show that social network features are useful for predicting the survival of communities but not for predicting their growth.
