ACL Anthology Reference Corpus is a digital archive of 10,291 research papers in computational linguistics sponsored by the Association for Computational Linguistics (ACL). This release contains most of the papers that appear up to February 2007 in the web-based ACL Anthology, a dynamic repository that currently hosts over 16,500 articles drawn from a range of conferences and workshops as well as past issues of the Computational Linguistics journal. See more on the Data Linguistic Consorcium web.

  • Version 20090501: This is the old version distributed by the Linguistic Data Consortium (LDC). This corpus is a canonicalized subset of the ACL Anthology, up to February 2007, consisting of 10,921 articles. This version adds page images in both text and image forms, as created by running OCR over the PDF files (Nuance Omnipage 15 or 16). For detailed information about the citation structure, do see the related project, Anthology Author Network (see below).
    [ DVD Disc 1 ] – Interlink data (clean), XML metadata (not clean, from Anthology), Image files in PNG format, text files from Omnipage in formatted and normal styles.

    If you have a copy of the ACL ARC from LDC, you may be missing some of the key files, files that give the textual dump of each page in three different formats. Here are a few quick links to the files:
