The Association for Computational Linguistics invites the submission of papers for its 43rd Annual Meeting hosted jointly with the North American Chapter of the ACL. Papers are invited on substantial, original, and unpublished research on all aspects of computational linguistics, including, but not limited to: pragmatics, discourse, semantics, syntax, grammars and the lexicon; phonetics, phonology and morphology; lexical semantics and ontologies; word segmentation, tagging and chunking; parsing, generation and summarization; language modeling, spoken language recognition and understanding; linguistic, psychological and mathematical models of language; language-oriented information retrieval, question answering, and information extraction; machine learning for natural language; corpus-based modeling of language, discourse and dialogue; multi-lingual processing, machine translation and translation aids; multi-modal and natural language interfaces and dialogue systems; applications, tools and resources; and evaluation of systems.

Requirements

Papers should describe original work; they should emphasize completed work rather than intended work, and should indicate clearly the state of completion of the reported results. Wherever appropriate, concrete evaluation results should be included. Submissions will be judged on correctness, originality, technical strength, significance and relevance to the conference, and interest to the attendees.

A paper accepted for presentation at the ACL Meeting, including ACL-related workshops and conferences, cannot be presented or have been presented at any other meeting with publicly available published proceedings. Papers that are being submitted to other conferences or workshops must indicate this on the title page, as must papers that contain significant overlap with previously published work.

Reviewing

The reviewing of the papers will be blind. Reviewing will be managed by an international Conference Program Committee consisting of Area Chairs and associated Program Committee Members. Final decisions on the technical program will be made by a meeting of the Program Co-Chairs and Area Chairs. Each submission will be reviewed by at least three program committee members.

• Michael Collins (MIT, USA)
• Marti Hearst (UC Berkeley, USA)
• Hang Li (Microsoft Research Asia, China)
• Chin-Yew Lin (USC/Information Sciences Institute, USA)
• Yuji Matsumoto (Nara Institute of Science and Technology, Japan)
• Diana McCarthy (University of Sussex, UK)
• Hermann Ney (RWTH Aachen, Germany)
• Gerald Penn (University of Toronto, Canada)
• Brian Roark (Oregon Health & Science University, USA)
• Michael Strube (EML Research, Germany)

Submission Information

Submissions should follow the two-column format of ACL proceedings and should not exceed eight (8) pages, including references. We strongly recommend the use of ACL LaTeX style files or Microsoft Word Style files tailored for this year's conference. They are available at http://www.aclweb.org/acl2005/styles/. A description of the format is also available in case you are unable to use these style files directly. Papers must conform to the official ACL-05 style guidelines, and we reserve the right to reject submissions that do not conform to these styles including font size restrictions.

As reviewing will be blind, the paper should not include the authors' names and affiliations. Furthermore, self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ...", should be avoided. Instead, use citations such as "Smith previously showed (Smith, 1991) ...". Papers that do not conform to these requirements will be rejected without review.

Submission will be electronic using the paper submission software available at http://www.softconf.com/start/ACL05/submit.html. The only accepted format for submitted papers is Adobe PDF. The papers must be submitted no later than 5pm US Eastern time January 14, 2005 (10pm GMT January 14, 2005). Papers submitted after that time will not be reviewed. Please consult the submission webpage for details of the submission procedure. Questions regarding the submission procedure should be directed to the Program Co-Chairs ( ).

Mentoring Service

ACL is providing a mentoring (coaching) service for authors from regions of the world where English is not the language of scientific exchange. Many authors from these regions, although able to read the scientific literature in English, have little or no experience in writing papers in English for conferences such as the ACL meetings. The service will be arranged as follows. A set of potential mentors will be identified by Richard Power, who has agreed to organize this service for ACL-05. If you would like to take advantage of the service, send a draft of your paper to:

To take advantage of this service, send the paper electronically to the above email address, using pdf, ps or doc format. Alternatively, hard copy can be sent to the postal address. The paper should arrive before December 14, 2004. An appropriate mentor will be assigned to your paper and the mentor will get back to you by January 7, 2005, at least seven days before the deadline for the submission to ACL-05 program committee. Please note that this service is for the benefit of the authors as described above. It is not a general mentoring service for authors to improve their papers.

If you have any questions about this service please feel free to send a message to Richard Power.

Conference Venue

The University of Michigan, Ann Arbor, is one of the largest, most diverse, and most prestigious centers of learning in the United States. Ann Arbor is easy to reach by air, rail, or highway. An Amtrak station is located less than two miles from the University of Michigan, and Detroit Metropolitan Airport is a brief 30-minute drive. The conference meetings will be held at the Michigan League on Central Campus. A conveniently located email/internet room will be provided to participants. Lodging will be in local hotels and dormitories.
