■ Author Registration Policy
Accepted refereed papers, posters, and demos must be presented at the conference by an author who is registered to attend. Accepted papers, posters, and demos of non-registered authors will be withdrawn from the program and the conference proceedings without exception. Authors are encouraged to visit http://www.www2011india.com/visa.html regarding visa requirements for India.
At least one author should register by 28th February 2011.

■ Language Policy
English is the official language of the conference. All papers, posters, and demos presented must be in English.

■ Copyright Policy
Accepted refereed papers will appear in the conference proceedings published by the Association for Computing Machinery (ACM), and will also be accessible to the general public on the WWW 2011 web site. Authors of accepted papers are required to sign the IW3C2 Copyright Release Form. Poster and demo authors are not required to transfer copyright.

■ Simultaneous Submission Policy
Submitting the Paper as a Poster is not allowed.  A Poster submission is considered to be the same as a Paper submission if the main technical content of the Poster submission is a subset of the Paper submission.  Authors will have an option to ask their Paper submissions to be considered for the Posters track, in case the Paper submission is rejected.

However, it is acceptable for a demo submission to overlap with either a Paper or  a Poster submission.

■ Duplicate Submission Policy
Duplicate submissions are not allowed. A submission is considered to be a duplicate if, at any time during the time when the submission is under consideration, there is another paper with the following properties:
1. the paper and the WWW submission have at least one author in common;
2. the paper is more than 4 pages long, when formatted in the WWW format;
3. the main technical content of the paper substantially overlaps that of the WWW submission; and
4. the paper is published or under consideration for publication in a refereed journal or proceedings (electronic or printed) that is generally available (e.g., not limited to conference attendees).

Authors are expected to agree to the following terms:

I understand that the paper being submitted must not overlap substantially with any other paper that I am a co-author of and that  is currently submitted elsewhere. Furthermore, previously published  papers with any overlap are covered prominently in this submission.

Duplicate submissions will be rejected. Questions about this policy or how it applies to your work should be directed to the program chairs.
