eu_procurements: EU procurement contract networks (2008-2016)
A bipartite network of public EU procurement contracts, from 2008 to 2016, between issuing buyers (public institutions such as a ministry or city hall) and supplying winners (a private firm). Contracts are aggregated into annual snapshots, edges are annotated with contract value information. Nodes are annotated with location information, including country of origin.
This network has 839824 nodes and 4098711 edges.

freshmen: Zeggelink's freshmen (1999)
Snapshots of friendships among freshmen majoring in Sociology at the University of Groningen, collected five times over the 1998-1999 year. The direction of an edge indicates that student i is friends with student j, and the edge weight gives their friendship level from 1 (best friend) to 5 (troubled relation). Metadata include gender, age, program type, and smoking behavior.
This network has 34 nodes and 1156 edges.

Random walk based snapshot clustering for detecting community dynamics in temporal networks
The evolution of many dynamical systems that describe relationships or interactions between objects can be effectively modeled by temporal networks, which are typically represented as a sequence of static network snapshots. In this paper, we introduce a novel random walk-based approach that can identify clusters of time-snapshots in which network community structures are stable. This allows us to detect significant structural shifts over time, such as the splitting or merging of communities or …

cora: CORA citations (1998)
Citations among papers indexed by CORA, from 1998, an early computer science research paper search engine. If a paper i cites a paper j also in this data set, then a directed edge connects i to j. (Papers not in the data set are excluded.) Self-loops may be present. The dates of these snapshots are uncertain.
