The International Conference on Weblogs and Social Media is a unique forum that brings together researchers from the disciplines in computer science, linguistics, communication, and the social sciences. The broad goal of ICWSM is to increase understanding of social media in all its incarnations. Submissions describing research that blends social science and technology are especially encouraged.

Though this conference is relatively new, it has become one of the premier venues for social scientists and technologists to gather and discuss cutting-edge research in Social Media. This is largely due to a typical acceptance rate of 20% for full-length research papers and support from Association for the Advancement of Artificial Intelligence (AAAI).

For ICWSM-11, in addition to the usual program of contributed technical talks, tutorials and invited presentations, the main conference will include a selection of keynote talks from prominent social scientists and technologists. This year, for the first time, we will be expanding our workshop program and are planning an additional workshop day in addition to the usual tutorial and main conference. We have a received a number of exciting workshop proposals already and are looking forward to receiving many more. Also, since we will be collocating with IJCAI (for more details on IJCAI-11 see there will be opportunities to connect with people in that community both formally and informally (joint social event is in the planning!).



Topics Include


Author Registration

Authors must register at the ICWSM-11 web-based technical paper submission site ( The software will assign a password, which will enable the author to log on to submit an abstract and paper. In order to avoid a rush at the last minute, authors are encouraged to register as soon as possible, and well in advance of the January 31, 2011 abstract deadline.

Abstract and Paper Submission

Electronic abstract submission through the ICWSM-11 paper submission site ( is required on or preferably before January 31, 2011 at 11:59 PM PST. Full papers are due via the submission site no later than Monday, February 7, 2011 at Midnight PST. We cannot accept submissions by e-mail or fax.
Authors will receive confirmation of receipt of their abstracts and papers, including an ID number, shortly after submission. AAAI will contact authors again only if problems are encountered with papers.

Content Guidelines

Submissions to to other conferences or journals: ICWSM-11 will not accept any paper that, at the time of submission, is under review for or has already been published or accepted for publication in a journal or conference. This restriction does not apply to submissions for workshops and other venues with a limited audience. If in doubt please contact the PC Chairs.

If duplicate submissions are identified during the review process then:

Format:Papers must be in trouble-free, high resolution PDF format, formatted for US Letter (8.5" x 11") paper, using Type 1 or TrueType fonts. Full papers must be no longer than 8 pages, including references, poster papers must be no longer than 4 pages, and demo descriptions must be no longer than 2 pages, and all must be submitted by the deadlines given above, and formatted in AAAI two-column, camera-ready style (see the author instructions page ). Please note that the formatting and submission instructions at the author site are for final, accepted papers; no additional pages can be purchased at the review stage. In addition, the copyright slug may be omitted in the initial submission phase and no copyright form is required until a paper is accepted for publication.

Anonymity: ICWSM 2011 review is double-blind. Therefore, please anonymize your submission: do not put the author(s) names or affiliation(s) at the start of the paper, and do not include funding or other acknowledgments in papers submitted for review. Citations to authorsí own prior relevant work should be included, either by not specifying that this is the authorsí own work, or where this is not possible, by anonymizing the citation itself. It is up to the authors' discretion how much to further modify the body of the paper to preserve anonymity. The requirement for anonymity does not extend outside of the review process, e.g. the authors can decide how widely to distribute their papers over the Internet before the program committee meeting. Even in cases where the authorís identity is known to a reviewer, the double blind process will serve as a symbolic reminder of the importance of evaluating the submitted work on its own merits without regard to authorsí reputation.

Language: All submissions must be in English.

Conference Registration

All accepted papers and extended abstracts will be published in the conference proceedings. At least one author must register for the conference by the deadline for camera-ready copy submission. In addition, the registered author must attend the conference to present the paper in person.


All accepted papers and abstracts will be allocated eight (8) pages in the conference proceedings. Authors will be required to transfer copyright of their paper to AAAI.
