Instructions for Camera-Ready Copy

The camera-ready copy of the accepted paper should follow the requirements in the above style file. These instructions are for authors of papers accepted by the main conference and workshops as oral or poster papers. Some general guidelines and a quick check list for publication requirements that conform to the specifications are provided here. Camera-ready copies that fail to meet these instructions may be returned for re-submission.

General Guidelines

All submissions must conform to the official ACL-IJCNLP 2009 style guidelines and they must be electronic in PDF.

Full papers should follow the two-column format of ACL-IJCNLP 2009 proceedings without exceeding eight (8) pages of content plus one extra page for references.

Short papers should also follow the same format, and should not exceed four (4) pages, including references. We strongly recommend the use of ACL LaTeX style files or Microsoft Word Style files tailored for this year's conference.

It is very important to specify A4 paper size. The page limit has to be strictly observed. DO NOT include page numbers. They will be generated when compiling the proceedings. All camera-ready manuscripts should look like the sample PDF file, which also contains detailed formatting requirements.

Camera-Ready Copy Submission Due

Main Conference, Full Papers: 17 May 2009 (GMT+8)
Main Conference, Short Papers: 7 June 2009 (GMT+8)
Workshops Papers: 7 June 2009 (GMT+8)

Quick Check List for Camera-Ready Papers

Some important instructions are explained further in the following sections.
See also the style file for other details.

Title and Author Names Registered to the Submission System

When author names are registered to the electronical submission system (and the final camera-ready copy), they should not be formatted in all capitals (e.g., use "Schlangen" not "SCHLANGEN"). Furthermore, the first name should be given first (i.e., use "Alfred V. Aho" instead of "Aho, Alfred V." or "Aho, A. V.").

Do not format title and section headings in all capitals as well except for proper names (such as "BLEU") that are conventionally in all capitals.

Title and Author Names for Camera-Ready Copy

The title, author names and addresses in the final camera-ready copy should be completely identical to those entered to the electronical paper submission website in order to maintain the consistency of author information among all publications of the conference.

When and where do I send my final camera-ready paper?

The deadline for full papers is May 17, 2009 (GMT+8). And, the deadline for short papers is June 7, 2009 (GMT+8). You may upload your paper via the START Conference Manager:

Please double check that all meta-data (author names, affiliations, paper title, etc) are entered into the system correctly and exactly as they appear on the paper, especially if they contain non-ASCII characters.

How should the final copy differ from the original submission?

The paper should be improved to address the comments of the reviewers, and in any other way that you see fit. The final version should, of course, not be anonymous:

  • Include the authors' names and affiliations under the title
  • De-anonymize references to your own work
  • Add acknowledgments where appropriate

How long can it be?

At most 8 pages of text; one additional page containing only references is permitted. Short papers get 4 pages of text total (no additional page for references).

What is the format for the camera-ready copy?

The file must be in Portable Document Format (PDF) on A4 paper (210 x 297 millimeters or 8.3 x 11.7 inches). Style files and detailed formatting instructions have been updated since the submission deadline, so please download the latest version indicated in the above style files table.

If you are using LaTeX, please create the PDF file with pdflatex. This ensures use of the proper Type 1 fonts and also takes advantage of other PDF features. (If you can't use pdflatex for some reason, use latex, and then turn the resulting dvi file into pdf with dvips -Ppdf (do not use dvips -Pps). If A4 output is not the default for your installation of dvips, add -t a4 to specify the output format. See here for a comparison of latex vs. pdflatex.)

How do I ensure that my file is correctly formatted?

Please check the paper size by viewing your document in Acrobat Reader. The bottom of the window should show the size as "8.3 x 11.7 in" or "210 x 297 mm" or "A4." If you are using pdflatex to create the pdf, A4 should be the default. If it's not, you can change it as described here. If you are using latex / dvips, see above.

If your paper uses Asian fonts, please ensure that they are encoded/embedded in the PDF file so that they can be displayed by non-Asian versions of the PDF reader. (Asian versions ship with a larger set of default fonts.) See Adobe's discussion of this issue, which unfortunately does not discuss LaTeX. Suggested diagnostics and solutions are welcomed.

What if my paper includes graphics?

Remember that you are providing a camera-ready copy. Thus, artwork and photos should be included directly in the paper in their final positions. Resolution for raster images should be at least 160 dpi. Avoid GIF or JPEG images that are low resolution or highly compressed. If images contain screen gradients, do not use screen values below 20%.

Your paper must look good both when printed (A4 / 8.3" x 11.7" size, black-and-white) and when viewed onscreen as PDF (zoomable to any size, color okay). Thus, you may want to use color high-resolution graphics, allowing onscreen readers to zoom in on a graph and study it. However, please check that the same graph or photograph is legible when printed on a black-and-white printer. For example, different lines in a graph should not be distinguished only by color, although they can also be distinguished by color.

A good test is to print the paper on your own black-and-white laser printer, and to view it in a PDF viewer at different resolutions.

Don't go overboard on resolution; keep file sizes manageable. Note that vector graphics (e.g., encapsulated PostScript) look good at any scale and take up little space (unless you are plotting many thousands of data points).

How about copyright?

When you submit the paper, you will be asked to sign electronically (via the START Conference Manager) or physically the ACL-AFNLP Copyright Transfer Agreement on behalf of all authors. Authors retain many rights under this agreement. If the agreement is not signed or not signed properly, your paper may not be included to the proceedings and other media. Authors who cannot make the copyright transfer, as indicated by the exceptional cases of the above Copyright Transfer Agreement, should acquire an authorized "License to Publish" or any equivalent forms from their institutes or employers, and forward the license to the PC chairs at sujian[at] and wiebe[at] as soon as possible. (Authors of workshop papers, if requested, should send the license to their respective workshop PC chairs.) In case of any problem with copyright transfer, please contact the publications chairs as soon as possible.

Before signing this form, please confirm with your co-authors (and, if applicable, your and their employers) that they authorize you to sign on their behalf.

What if my paper's title or author list has changed?

Then please edit those metadata fields when you upload the camera-ready version, so that they will appear correctly in the table of contents, author index, conference schedule, etc.

My question isn't answered here ...?

Please email the publications chairs Regina Barzilay (regina[at] and Jing-Shin Chang (jshin[at] We will update this page as new issues arise.
