Sequential detection of temporal communities by estrangement confinement

Abstract: Temporal communities are the result of a consistent partitioning of nodes across multiple snapshots of an evolving network, and they provide insights into how dense clusters in a network emerge, combine, split and decay over time. To reliably detect temporal communities we need to not only find a good community partition in a given snapshot but also ensure that it bears some similarity to the partition(s) found in the previous snapshot(s), a particularly difficult task given the extreme sensitivity of communit… Show more

“…In this subsection, we report the results of performing community detection on the two real dynamic datasets introduced in Subsection IV-A by using the dynamic community detection algorithms, LabelRankT [20] and Estrangement [17]. LabelRankT [20] detects communities in large-scale dynamic networks through stabilized label propagation.…”

“…As a baseline for comparison, we applied three wellknown community mining algorithms of different approaches. These methods are FacetNet [16] , Estrangement [34] and static clustering using FUA method [4]. The static method does not consider any temporal evolution and is applied on each snapshot independently.…”

“…In their proposed framework, the community structure of the current snapshot is detected by incorporating the current graph structure and historic community evolution patterns [33]. Recently, Kawadia and Sreenivasan [34] have proposed a new measure called "Estrangement" to quantify the partition distance between two consecutive timesteps. They describe estrangement as "the fraction of intracommunity edges that become inter-community edges as the network evolves to the subsequent snapshot".…”
