SIGIR 2007: Call for Posters and Call for Demonstrations The 30th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval 23-27 July 2007, Amsterdam, The Netherlands http://www.sigir2007.org SIGIR is the major international forum for the presentation of new research results and for the demonstration of new systems and techniques in the broad field of information retrieval (IR). The Conference and Program Chairs invite all those working in areas related to IR to submit original research contributions, posters, and demonstrations of systems. *CALL FOR POSTERS* Poster presentations offer researchers a unique opportunity to present late-breaking results, significant work in progress, or research that is best communicated in an interactive or graphical format. They further provide researchers with an opportunity to obtain direct feedback about their work from a wide range of persons during the poster session. Posters should focus on problems and methodology of the presented research. Extended abstracts describing the work will be reviewed and published in the conference proceedings. Please note however, that posters describing work at the proposal stage will not be accepted. Submissions of extended abstracts for posters must be in English and should not exceed 2 pages in SIGIR format (including references and figures). Suitable LaTeX and Word templates for SIGIR are available from the ACM Website. The only accepted form for submissions are PDF files, which need to be uploaded via the SIGIR electronic submission web page. As with full papers, authors are encouraged to conceal their identity where it is practical to do so. Submissions need to be received by February 25, 2007. Late submissions will be rejected without further consideration. *CALL FOR DEMONSTRATIONS* Demonstrations present first-hand experience with research prototypes or operational systems. They provide opportunities to exchange ideas gained from implementing IR systems and to obtain feedback from expert users. Demonstration submissions are welcomed in any of the areas identified in the call for papers. One-page demonstration abstracts will appear in the conference proceedings. Submissions must be in English and consist of an extended abstract (one page in SIGIR format including references and figures) and an additional one-page requirements description. The abstract should emphasize what the implemented system aims to achieve, the major components of the system, the novelty of the techniques that have been implemented, and comparisons with comparable systems. The requirements description should identify the hardware, software and network access requirements for the demonstration. Network connections and computers with standard Web browsers can be provided upon request. Proposals to demonstrate systems that require more than a standard Web browser (e.g. context-aware mobile systems or virtual reality systems) must explain how the systems will be demonstrated at the conference. Submissions should be in PDF format. Unlike posters and research papers, authors of demonstration proposals are not expected to take measures to conceal their identity from reviewers. Demonstration proposals must be submitted by February 25, 2007. *IMPORTANT DATES* January 28, 2007: Full research papers due February 25, 2007: Poster, demonstration, tutorial, and workshop submissions March 11, 2007: Doctoral consortium submissions due April 11, 2007: Notification of acceptance for all submissions July 23-27, 2007: Conference in Amsterdam See also: http://www.sigir2007.org/cfp.html Syndication: http://www.sigir2007.org/news/feed.rss Mailinglist: Send SUBSCRIBE to sigir07@cs.utwente.nl Contact: info@sigir2007.org
