CiteULike user–publication

About this network

This is the bipartite network of users and publications in CiteULike. Each edge represents a tag assignment that connects a users and a publication. Since a user can be assign multiple tags to a publication, the network contains multiple edges. The edges are annotated with the creation time of the tag assignment.
