CiteULike user–tag

About this network

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