CiteULike user–item
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.
