三角形捕捉社会凝聚力

Triangles to Capture Social Cohesion

Adrien Friggeri, Guillaume Chelius, Eric Fleury

摘要:

虽然社区发现在过去几十年中引起了科学界的极大关注,但对于什么是社区的本质还没有达成正式的共识。在这篇文章中,我们采取了正交的方法,通过引入一个新的观点,重叠社区的问题。而不是量化一组社区的质量,我们选择专注于一组给定节点的内在社区性。要做到这一点,我们提出了一个通用的度量图,凝聚力,基于计数三角形和完善的社会学考虑的启发。该模型已经通过一个名为Fellows的大规模在线实验进行了验证,在该实验中,用户能够计算他们在Facebook上的社交群体,并对所获得的群体的质量进行评级。通过观察这些评级的凝聚力,我们评估的凝聚力是一个很强的指标,用户的主观感知的社区性的一组人。

英文摘要:

Although community detection has drawn tremendous amount of attention across the sciences in the past decades, no formal consensus has been reached on the very nature of what qualifies a community as such. In this article we take an orthogonal approach by introducing a novel point of view to the problem of overlapping communities. Instead of quantifying the quality of a set of communities, we choose to focus on the intrinsic community-ness of one given set of nodes. To do so, we propose a general metric on graphs, the cohesion, based on counting triangles and inspired by well established sociological considerations. The model has been validated through a large-scale online experiment called Fellows in which users were able to compute their social groups on Face- book and rate the quality of the obtained groups. By observing those ratings in relation to the cohesion we assess that the cohesion is a strong indicator of users subjective perception of the community-ness of a set of people.
