Submission will be electronic, using the START paper submission webpage.

The only accepted formats for submitted papers are Adobe PDF and PostScript. The papers must be submitted no later than April 17, 2007 (24:00pm GMT-7). Papers submitted after that time might not be reviewed. Note that in the webpage you will be asked to choose between two types of submission: *task description* paper and *system description* paper. Please, choose accordingly.

Submissions should follow the regular format of ACL proceedings, with the following three exceptions:

1. Paper reviewing will not be blind, so you can include authors' names, affiliations and references in the submitted paper.
2. Page limits:
   • System description papers (task participants): 4 pages for the first system and 2 extra pages for each additional task, up to a maximum of 8 pages
   • Task description papers (task organizers): 6 pages
3. Paper titles:
   • System description papers (task participants): the title should start with the team ID followed by ":" (e.g "UBC-ALMB: WSD using ...")
   • Task description papers (task organizers): the title should start with "SemEval-2007 Task " and, ideally, be followed by the same name you used so far for your task (e.g., "SemEval-2007 Task 09: Multilevel Semantic Annotation of Catalan and Spanish").

If you think that your situation is exceptional in any way, contact SemEval-2007 organizers as soon as possible ().

Recall the upcoming deadlines regarding paper preparation:

• System description papers due: April 17, 2007
• Paper reviews due: April 27, 2007
• Camera-ready papers: May 6, 2007

Since we are running under a very tight schedule, all the above are hard deadlines. We cannot assure that papers failing to meet the deadlines or not conforming to the ACL styles can be reviewed and included in the SemEval-2007 proceedings.
