Clairlib
The Clair library (i.e. Clairlib) is a suite of open-source Perl modules intended to simplify a number of generic tasks in natural language processing (NLP), information retrieval (IR), and network analysis (NA). Its architecture also allows for external software to be plugged in with very little effort. To download, please visit www.clairlib.org

AAN: The AAN corpus includes three networks, paper citation, author citation and auth or collaboration. The paper citation network (paper-citation-network.txt) is a directed network composed of nodes labeled with paper ids which correspond to in dividual papers (acl-metadata.txt). The author citation network (author-citation-network.txt), a directed network, is compiled from the paper network and the metadata file. For each citation in the paper network, where paper A cites paper B, and for each author in paper A, an edge is created for that author to each author in paper B. The author collaboration network (author-collaboration-network.txt), an undirected network, is composed of authors where, for each paper in t he paper citation network, an edge is created between each collaborator for that paper.Download
