随着Meetup.com和Facebook Events等基于活动的社交网络（EBSNs）在管理当地活动（例如农贸市场和社交聚会）方面越来越受欢迎，活动组织者和参与者在相互影响的同时也从平台中受益，从而创造了双边文化利基。在众多因素中，生态位重叠作为一种生态特征，被研究为影响网络社区成功的关键因素。虽然这些生态因素也可能影响基于ebsn的地方群体的成功，但由于当地群体的非正式性质及其地理嵌入性，ebsn的背景在理解文化利基的作用方面提出了独特的挑战。在本文中，我们使用美国500个城市一年的Meetup数据，研究了Meetup小组的主题重叠和地理空间相关性对组织者和参与者活动水平的影响。研究发现：(1)一个群体在EBSN上与其他群体的主题重叠与其活动水平相关；(2)本地群体的地理空间相关性可能会调节EBSN用户的主题重叠效应，但不一致。结果提供了从生态学角度对基于ebsn的群体的基本理解。
As event-based social networks (EBSNs) such as Meetup.com and Facebook Events gain popularity in managing local events (e.g., farmers’ markets and social gatherings), two-sided cultural niches are created as event organizers and participants benefit from the platform while affecting each other. Among various factors, niche overlap, an ecological feature, has been studied as a key factor that shapes the success of online communities. While such ecological factors may also shape EBSN-based local groups’ success, the context of EBSNs raises unique challenges in understanding the roles of cultural niches due to the informal nature of the local groups and their geographical embeddedness. In this paper, we examine the effects of Meetup groups’ topic overlap and geospatial correlation on the activity levels of both organizers and participants, using one-year Meetup data for 500 cities in the United States. We find that (1) a group’s topic overlap with other groups on EBSN is associated with its activity levels, and (2) local groups’ geospatial correlation may moderate the effects of topic overlap for EBSN users, but inconsistently. The results provide a baseline understanding of EBSN-based groups from an ecological perspective.
