*ESWC 2009 Call for demonstrations/posters* 6th European Semantic Web Conference May 31 – June 4, 2009 Crete, Greece http://www.eswc2009.org/ The ESWC is the leading European conference on theory, practice and applications of Semantic Web technologies, attracting an increasing number of participants from various communities and sectors. *Call for demonstrations* The demonstrations track of the ESWC2009 complements the overall program of the conference with demonstrations of real-world, proven-and-tested advances of semantic technologies. In addition to papers and posters presenting latest theoretical achievements the ESWC2009 is seeking demonstrations of novel applications of semantics in various sectors, as well as innovative enabling technologies and deployment infrastructures relevant for the topics of interest defined for the main conference and the research and poster tracks. Submissions to the demonstrations track must be in form of a textual description of the demonstration to be given at the conference. The submissions must be maximally 3 pages long and formatted according to the Springer LNCS style. They should be submitted as PDF using the conference submission system. Accepted submissions to the demonstrations track will be published as part of the ESWC2009 proceedings. As such, the quality assurance will be strict, and the demonstrations will be subject to review by a separate Program Committee. Proposed demonstrations must show relevance, novelty and significance to the topics of the conference. The associated textual descriptions should contain sections answering the following questions, as appropriate: 1.What is the research background and application context of the demonstration? 2.What is the key technology used, and how does the demonstrated system, application or infrastructure relate to pre-existing work? What exactly will be demonstrated? What exactly will a visitor of the demonstration learn? *Call for posters* The poster track of the ESWC2009 will provide an opportunity for presenting late-breaking results, ongoing research projects, and speculative or innovative work in progress. Posters are intended to provide authors and participants with the ability to connect with each other and to engage in discussions about the work. Technical posters, reports on semantic systems, descriptions of completed work, and work in progress are equally welcome. Authors must submit a 2-page paper (PDF, Springer LNCS style) with a short abstract for evaluation. The paper must clearly demonstrate relevance to the Semantic Web and the topics of interest of ESWC2009. Submissions will be evaluated by a separate Program Committee. Decisions about acceptance will be based on relevance to the Semantic Web area, originality, potential significance, topicality and clarity. Papers that exceed the given page length or do not follow the LNCS guidelines risk being rejected without a review. Papers submitted to the research track will NOT automatically be considered for the poster track. A separate poster submission must be made. For example, a poster can be provided for an accepted paper or can be used to present work that was insufficiently mature for the research track. *Submission* Submission and reviewing of demonstrations and posters will be electronic via the ESWC2009 Demo EasyChair installation at http://www.easychair.org/conferences/?conf=eswc09demo and http://www.easychair.org/conferences/?conf=eswc09posters, respectively. *Important Dates* Submission (Demos): January 16, 2009 (11:59 pm Hawaii time) Notification (Demos): February 23, 2009 Camera Ready (Demos): March 09, 2009 Submission (Posters): March 23, 2009 (11:59 pm Hawaii time) Notification (Posters): April 20, 2009 Camera Ready (Posters): May 11, 2009
