The 6th Annual European Semantic Web Conference (ESWC2009) 31 May - 4 June 2009, Heraklion, Greece www.eswc2009.org The vision of the Semantic Web is to enhance today's Web by exploiting machine-processable metadata. The explicit representation of the semantics of data, enriched with domain theories (ontologies), will enable a web that provides a qualitatively new level of service. It will weave together a large network of human knowledge and makes this knowledge machine-processable. Various automated services will help the users to achieve their goals by accessing and processing information in machine-understandable form. This network of knowledge systems will ultimately lead to truly intelligent systems, which will be employed for various complex decision-making tasks. Semantic Web research can benefit from ideas and cross-fertilization with many other areas: Artificial Intelligence, Natural Language Processing, Databases and Information Systems, Information Retrieval, Multimedia, Distributed Systems, Social Networks and Web Engineering. Many advances within these areas can contribute towards the realization of the Semantic Web. The 6th Annual European Semantic Web Conference (ESWC2009) will present the latest results in research and applications of Semantic Web technologies. ESWC2009 will also feature a tutorial program, system descriptions and demos, a posters track, a PhD Symposium and a number of collocated workshops. The calls for these events are separate and can be found on the conference Web site (http://www.eswc2009.org/calls). ESWC2009 is sponsored by STI International, Semantic Technology Institutes International.

We particularly encourage the submission of papers on industrial efforts and experiences with Semantic Web projects. We encourage theoretical, methodological, empirical, and applications papers. The proceedings of this conference will be published in Springer's Lecture Notes in Computer Science series. Paper submission and reviewing for ESWC2009 will be electronic via the conference submissions site. Papers should not exceed fifteen (15) pages in length and must be formatted according to the information for LNCS authors. Papers must be submitted in PDF (Adobe's Portable Document Format) format and will *not* be accepted in any other format. Papers that exceed 15 pages or do not follow the LNCS guidelines risk being rejected automatically without a review. Authors of accepted papers will be required to provide semantic annotations for the abstract of their submission -- details of this process will be provided on the conference Web page at the time of acceptance. At least one author of each accepted paper must register for the conference. For more information about the Springer's Lecture Notes in Computer Science (LNCS) please visit: http://www.springer.com/computer/lncs?SGWID=0-164-7-72376-0 Papers have to be submitted electronically at: https://www.easychair.org/login.cgi?conf=eswc2009 Best Paper Award An award will be given to the best paper (or papers) submitted to the conference as judged by the Program Chairs in collaboration with the Program Committee.
