最近的研究表明，在离线情况下，空间接近增加了两个人建立在线社交联系的可能性，因此地理上的接近可能会影响在线社区的形成。在这项工作中，我们提出了一个研究的社区在两个在线社交网络的位置共享功能，并分析其社会和空间属性。我们研究用户访问的地方，以了解社区是否围绕着地方，或者它们是否独立存在。我们的研究结果表明，在社交网络的社区结构可能会产生的社会和空间因素，因此，利用人们去的地方的信息可以有利于新的社区检测方法和社区演化模型的定义。
Recent research suggests that, as in offline scenarios, spatial proximity increases the likelihood that two individuals establish an online social connection, and geographic closeness could therefore influence the formation of online communities. In this work we present a study of communities in two online social networks with location-sharing features and analyze their social and spatial properties. We study the places users visit to understand whether communities revolve around places or whether they exist independently. Our results suggest that community structure in social networks may arise from both social and spatial factors, so that exploiting information about the places where people go could benefit the definition of new community detection methods and community evolution models.
