ACL Anthology Reference Corpus (ACL ARC)

[ Back to the ACL home page ]
[ Back to WING ]

This is the home page of the ACL Anthology Reference Corpus, a corpus of scholarly publications about Computational Linguistics. This corpus is a canonicalized subset of the ACL Anthology, up to February 2007, consisting of 10,921 articles. We hope this frozen corpus will be used for benchmarking applications for scholarly and bibliometric data processing.

Version 20090501: This is the version distributed by the Linguistic Data Consortium (LDC). 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.
[ DVD Disc 2 ] - continuing PNG files.
[ DVD Disc 3 ] - remaining PNG files, PDFs from Anthology
[ DVD Disc 4 ] - remaining PDF files, text files from Omnipage in XML style.
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:
- [ data/txt/omnipage/normal.tgz ] - Normal, reading order text dump from Disc 1.
- [ data/txt/omnipage/xml.tgz ] - XML text dump, with formatting information, from Disc 4.
- [ data/txt/omnipage/formatted.tgz ] - formatted (2 column) text dump from Disc 1.
Version 20080325: This is the version described in the LREC paper that contains the canonical 10,921 computational linguistics papers as PDF and plain text files, with the associated metadata. (You can also email me to request a DVD copy of the corpus)
