Invitation for Submissions
The 50th Annual Meeting of the Association for Computational Linguistics and the Human Language Technologies conference will be organized as a single event to be held at the  International Convention Center Jeju, Jeju, Korea, on July 8-14, 2012. The conference will cover a broad spectrum of technical areas related to natural language and computation. ACL 2012 will include full papers, short papers, oral presentations, poster presentations, demonstrations, tutorials, and workshops. The conference is organized by the Association for Computational Linguistics.

The conference invites the submission of papers on original and unpublished research on all aspects of computational linguistics, including but not limited to:

1. Discourse, Dialogue, and Pragmatics
2. Information Extraction
3. Information Retrieval
4. Language Resources
5. Lexical Semantics
6. Lexicon and ontology development
7. Machine Translation
8. Multilinguality
9. Multimodal representations and processing
10. Social Media
11. Natural Language Processing Applications
12. Phonology/Morphology, Tagging and Chunking, Word Segmentation
13. Question Answering
14. Sentiment Analysis and Opinion Mining
15. Spoken Language Processing
16. Statistical and Machine Learning Methods
17. Summarization and Generation
18. Syntax and Parsing
19. Text Classification
20. Text Mining
21. User Studies and Evaluation Methods
Submission Information
Submissions must describe substantial, original, completed and unpublished work. Wherever appropriate, concrete evaluation and analysis should be included. Submissions will be judged on correctness, originality, technical strength, significance, relevance to the conference, and interest to the attendees.
ACL 2012 will also accept papers accompanied by the resource (software or data) described in the paper. In addition to the regular review of the research quality of the paper, these papers will also be reviewed for the quality of the resource that is being made available. Papers that are submitted with accompanying software/data will receive additional credit toward the overall evaluation score, and acceptance or rejection decision will be made based on the quality of both the research and the software/data component.
ACL 2012 has the goal of a broad technical program. We invite papers in the following four broad categories: theoretical computational linguistics, empirical/data-driven approaches, resources/evaluation, applications/tools. We also invite papers describing a challenge in the field, position papers, survey papers, and papers that describe a negative result.
Submission is electronic using paper submission software at:

Long papers: https://www.softconf.com/acl2012/papers/
Short papers: https://www.softconf.com/acl2012/shortpapers/

NOTE: Before submitting your paper, please make sure you read the review forms that will be used for the different paper categories.

1. Applications / Tools
2. Empirical / Data-Driven
3. Resources / Evaluation
4. Theoretical
5. None of the above

If you plan to also submit a software package or a dataset along with the paper, please upload the software/data in the submission form.
Long papers
Long papers may consist of up to eight (8) pages of content, with two (2) additional pages of references, and will be presented orally or as a poster presentation as determined by the program committee. The decisions as to which papers will be presented orally and which as poster presentations will be based on the nature rather than on the quality of the work. There will be no distinction in the proceedings between full papers presented orally and those presented as poster presentations. The deadline for long papers is 15th January, 2012 (11:59pm PST).
Short papers
Short papers may consist of up to four (4) pages of content, and two (2) additional pages of references. Short papers will be published in a separate volume, and will be presented orally or as a poster presentations. The deadline for short papers is 18th March , 2012 (11:59pm PST). The following types of papers are appropriate for a short paper submission:
1. A small, focused contribution
2. Work in progress
3. A negative result
4. An opinion piece
5. An interesting application nugget
Format
Both long and short paper submissions should follow the two-column format. We strongly recommend the use of ACL LaTeX style files or Microsoft Word style files tailored for this year's conference, which are available on the conference website under Information for Authors. Submissions must conform to the official ACL 2012 style guidelines, which are contained in the style files, and they must be electronic in PDF.
As the reviewing will be blind, the paper must not include the authors' names and affiliations. Furthermore, self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ...", must 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. Authors that choose to also submit the supporting software/data with their paper, will have to ensure that the resource is ready for distribution, with complete README files and all the information required so that the reviewers can evaluate and/or use at least a part of the resource. The software/data component has to be anonymized for the review process. The resource associated with papers being accepted for publication at ACL 2012 will be publicly distributed along with the online version of the conference proceedings.

Multiple-submission policy

Papers that have been or will be submitted to other meetings or publications must provide this information at submission time. If ACL 2012 accepts a paper, authors must notify the program chairs, indicating which meeting they choose for presentation of their work. ACL 2012 cannot accept for publication or presentation work that will be (or has been) published elsewhere.

NEW INFORMATION: Because of concerns of reviewer overload, the program committees for ACL 2012 and NAACL 2012, along with the ACL Executive Board and NAACL Executive Board have decided to not allow double submission to each other's conferences. Submissions will be compared across these two conferences; papers with substantial overlap in their technical contributions that are submitted to both ACL 2012 and NAACL 2012 will be rejected without review at the discretion of the program committees.

Mentoring Service
ACL is providing a mentoring (coaching) service for authors from regions of the world where English is less emphasized as a 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. If you would like to take advantage of the service, for long papers, please send your intent and an abstract to Joyce Chai (jchai at cse.msu.edu) by November 11, 2011, and upload your full paper by November 25, 2011 using the paper submission portal for the mentoring service below; for short papers, please send your intent and an abstract to Joyce Chai by January 17, 2012, and upload your full paper by January 24, 2012. Questions about the mentoring service should be referred to Joyce Chai (jchai at cse.msu.edu).
