• Citing: Please do not publish the actual links to this site in print publications, as these may change over time. Instead, use Digital Object Identifiers (DOIs) for newer materials (post-2015), or the persistent URL for older materials (pre-2015) e.g., http://www.aclweb.org/anthology/E91-1001 (thanks to Dragomir Radev and Haejoong Lee for the latter). Both the DOIs and the persistent URLs embed the 8-character ACL Anthology Identifier.
  • Copyright: The ACL materials that are hosted in the Anthology are licensed to the general public under a liberal usage policy that allows unlimited reproduction, distribution and hosting of materials on any other website or medium, for non-commercial purposes. Prior to 2016, all ACL materials are licensed using Creative Commons 3.0 BY-NC-SA (Attribution, Non-Commercial, Share-Alike) license. As of 2016, this policy has been relaxed further, and all subsequent materials are available to the general public on the terms of the Creative Commons 4.0 BY (Attribution) license; this means both commercial and non-commercial use is explicitly licensed to all.

    Note that these policies only cover ACL materials. As with the DOIs, this policy does not cover third-party materials. For reproduction privileges for such materials, please approach the respective organizations.

  • Digital Object Identifiers: The ACL uses DOIs to refer to scholarly works persistently in accordance with cross-disciplinary standards. Prior to 2012, ACL materials were assigned DOIs by the Association of Computational Machinery (ACM). Since 2014, ACL has assigned its own DOIs to materials using a convention based off of the ACL Anthology Identifiers. In 2015, ACL had to change DOI prefix due to accounting practices for the ACM.
    • 2014-2015: 10.3115
    • 2015-current: 10.18653
    We strongly encourage the publication of DOIs in citing bibliographies to help better cross-reference ACL materials.

    Note while the ACL Anthology hosts third-party materials coming from sister societies, these materials are hosted courtesy the ACL but are not assigned DOIs by the ACL due to costs and copyright limitations; the DOI information above is only applicable to ACL sponsored events by ACL, its chapters or SIGs.

  • Software: The ACL Anthology is running on completely open-source software, with further developments and customization done by the ACL Anthology staff. The Anthology is a database-backed web application coded in Ruby on Rails and using the Project Blacklight for faceted browsing with underlying Java Lucene for searching. The source code for running the Anthology is available on GitHub: https://github.com/WING-NUS/acl
