(Not-so) Frequently Asked Questions
Everything else about your ACL Anthology
- Citing: Please do not publish the actual links to this site in print publications, as these may change over time.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
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.
- Plain Text: ASCII text and other metadata for a controlled subset of the Anthology.

- 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
