3 Foreword The Innovative Internet Community Systems (I 2 CS) moved successfully from a national workshop, founded in 2001, towards a small but remarkable international conference. Alternately, an international and a German location are selected by the steering committee for the annual three-day event which takes place in the second half of June. Its name is its mission: scientists, researchers, service providers and vendors form a great community which returns from Thailand s to German s capital in Two years ago, the conference has started a close corporation with the Gesellschaft für Informatik e.v. (GI) to publish the presented papers as Lecture Notes in Informatics (LNI) proceedings. A strong peer review by three to four members of the program committee guarantees the high quality of contributions. The present proceedings are structured in six topics, covering the selection of the best submitted papers from 2011 and limited unpublished papers from Please refer to LNI P-165 and P-148 for the previous I 2 CS proceedings. To receive a copy of a dedicated volume, please your request to lni@i2cs-conference.org. The bandwidth of I 2 CS topics for 2011 covers a unique choice of aspects, bundled into the three traditional areas: foundations, technology, applications and socialization. For the first time, ehealth appears as new social community challenge. Foundations Theories, models, algorithms for communities Distributed algorithms and simulation models Game theory, graph theory and cost models Innovative communication protocols Self organizationand self stabilization Security and privacy protection Swarm intelligence and collaborative behaviour Small world models and clouds

4 Technology Distributed architectures and frameworks Service-oriented architectures for communities Peer-to-peer and grid architectures Distributed community middleware for Web x.0 Software agents and adaptivesystems ehealth challenges and ambient assisted living Community management in ad-hoc environments Information retrieval and distributed ontologies Applications and socialization Communities on the move Mobile Internet applications and user experience Context and location awareness Personalization and unique identifiers Personal networks and social search Social and business aspects of user generated content Recommender solutions and expert profiles Domain specific languages for semantic design Many thanks to the members of the program committee and all volunteers, especially to Christian Erfurth, University of Applied Sciences Jena, Nicole Kandschur, Technische Universität Berlin, as well as Gracy Schröder, Deutsche Telekom Laboratories for their flexible support during the conference preparation. Also to those former authors who rewrote their papers according to the LNI style and gave their permission for publication of the contributions within this edition. The 12 th I 2 CS conference, carried out by the Norwegian University of Science and Technology (NTNU), will take place in Trondheim, Norway from June 20 till 22, Please check the permanent conference URL regularly for more details. Any new ideas and proposals for the future of the I 2 CS are welcome to request@i2cs-conference.org. With kind regards on behalfof the steering committee and the editors board Gerald Eichler, volume editor in chief Deutsche Telekom AG, Laboratories, Berlin & Darmstadt, Germany Darmstadt, June 2011

5 Preface to the 11 th I 2 CS 2011, Berlin, Germany It is a great pleasure for us to welcome all participants of the 11 th International Conference on Innovative Internet Community Systems I 2 CS 2011 to Berlin. On behalf of the organizing and program committee, we hope that you will have nice and unforgettable days in Germany s multi-cultural capital. "Research drives Innovation" is the motto of the 11 th I 2 CS, dedicated to challenging aspects around modern community systems. "With its alignment as central research and development unit of Deutsche Telekom on the one hand and a scientific institute associated with TU Berlin on the other, Deutsche Telekom Laboratories will be an excellent conference host. The selected venue, the Auditorium on the 20 th floor of Berlin s first skyscraper, will provide all facilities needed for such an event. Following the initial concept to keep the conference small and make it possible that all participants get to know each other, we selected 18 full papers for presentation at the plenary. It is the culture of I 2 CS to bring participants together, not only in order to share their latest results and experiences, but also to get to know and to learn about each other. We won t contribute to the tendency that conferences just serve the purpose to increase the authors publication count, butwould like to offer an inspired and unique atmosphere in which everybody will feel comfortable. As the last I 2 CS events have shown, this guarantees an excellent platform to live the community idea. Hence, participants will not only attend our scientific sessions, but will also spend as much time as possible together to discuss, share opinions or define projects ideas in brainstorming meetings. Last but not least, a well-chosen cultural program around our sessions will give the participants the possibility to get in contact with German s capital. We are happy that over the years a lot of colleagues join our conferences again and again, but in the same manner we appreciate and welcome all people who participate in I 2 CS for the first time and hope that this will not remain the only contact to our community. Beside a lot of contacts and meetings, the next year I 2 CS conference in Trondheim (Norway) may be therefore just another fix point where we can all meet again.
