ACL Anthology Reference Corpus

<h3>Introduction</h3><br>
<p>ACL Anthology Reference Corpus is a digital archive of 10,291 research papers in computational linguistics sponsored by the Association for Computational Linguistics (ACL). Also <a href="http://acl-arc.comp.nus.edu.sg/" rel="nofollow">available from the ACL</a>, this release contains most of the papers that appear up to February 2007 in the web-based <a href="http://aclanthology.info/" rel="nofollow">ACL Anthology</a>, 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 <em>Computational Linguistics</em> journal. The ACL Anthology Reference Corpus is designed to be a standard, real-world digital collection testbed for experiments in bibliographic and bibliometric research.</p><br>
<p>The ACL is the international scientific and professional society for scholars working on problems involving natural language and computation. Membership includes the ACL quarterly journal, <em>Computational Linguistics</em>, reduced registration at most ACL-sponsored conferences, discounts on ACL-sponsored publications and participation in ACL Special Interest Groups. Since 1988, <em>Computational Linguistics</em> has been the primary forum for research on computational linguistics and natural language processing.</p><br>
<h3>Data</h3><br>
<p>The material in the ACL Anthology Reference Corpus was scanned at 600dpi grayscale for archival storage, down-sampled to 300dpi black-and-white, assembled into articles and stored in the "PDF Image with Hidden Text" format. Author and title metadata was extracted from the OCRed text and used to build HTML index pages. Older materials, such as conference proceedings from the 1960s and early volumes of <em>Computational Linguistics</em>, were manually digitized from microfiche slides.</p><br>
<p>ACL Reference Anthology includes:</p><br>
<ul><br>
<li>10,921 PDF files in the pdf/anthology-PDF tree.</li><br>
<li>13,551 files with metadata described in the metadata/anthology-XML tree</li><br>
<li>84,542 pages in the PDF files</li><br>
</ul></br>
