The ACL Network was originally created by Mark Thomas Joseph and is currently being maintained by Luke Brandl under the supervision of Professor Dragomir R. Radev.


A number of students from the University of Michigan's CLAIR Group helped with the work involved to create the data, network, and webpages. We would like to thank:

About the Data

The ACL Anthology Network was built from the original pdf files available from the ACL Anthology. Using open source OCR technologies, in-house clean-up scripts, and often tedious manual labor, a web interface was developed that allowed for the annotation of individual references from each paper. We use the following tools for curation.

A Note About the PageRank Centrality

Because of the nature of PageRank values, we have adjusted the results to make them more human readable. The actual value of any PageRank on this website can be found by dividing the numbers given by 1,000,000. We also truncate the decimal points, leaving instead only the integer value. So, for example, if a paper has a computed PageRank of 0.003456789 , We would print that PageRank as 3456 after dropping the .789.
