The main output will be a Web portal that will buiild a social network of computer scientists., which will differ from the usual social and professional networks as Facebook or LinkedIn by providing unique tools to search for IT specialists, to create teams (for joint projects, tenders), and in general to allow cooperation. The aim of the project activities is to increase the competitiveness of the Czech Republic in the field of computer science, as well as improvement of the status of IT in the Czech Republic and its contribution to society. Personal interconnection of educational and research activities and the cooperation of academic and applied research are required for high-quality tertiary education and its fruitful cooperation with industry and Government. From the social network will benefit students and graduates, scientific personnel, schools, and businesses. It will be possible to search here for a job or an interesting project, skilled workers or whole teams, even the schools can compare their learning plans with the situation on the labor market. Beta-version of the portal will be available from April 2011, but now it is possible to test partial functionality (scientific profile) on: http://www.sosirecr.cz/forms/sciprof/. Another component of the project is to support personal meeting of the IT experts in the regions (both among themselves and with companies), the sharing of experience and the identification of needs. These are the conferences, regional seminars and workshops, aimed at improving communication between the academic, corporate and public sector. One of the following activities are for example Conversations with computer scientists (Hovory s informatiky), organised in the framework of this project by Institute of Computer Science, Academy of Sciences of the CR. On the SoSIReČR project cooperate: Faculty of Mathematics and Physics, Charles University in Prague Institute of Computer Science, Academy of Sciences of the Czech Republic Czech Technical University in Prague The Faculty of Informatics and Statistics, University of Economics, Prague Higher Vocational School and Technical High School, Šumperk Project (no CZ.07/2.4.00/12.0039) is running in period 01.11.2009 - 31.10.2012.

The 11th year was organized by Department of Computer Science VŠB- Technical University Ostrava, Department of Software Engineering MFF UK Praha, Department of Computer Science and Engineering FEL ČVUT Praha, and the Working group on Computer Science and Society of Czech Society for Cybernetics and Informatics. The DATESO workshops aim for strengthening connections between these various areas of Computer science. The proceedings of DATESO 2011 are also available at DATESO Web site: http://www.cs.vsb.cz/dateso/2011/ and CEUR Workshop Proceeding site: http://www.ceur-ws.org/Vol-706/ (ISSN 1613-0073). The Program Com- mittee selected 22 papers (12 full papers, 4 special session full papers and 6 posters) from 33 submissions, based on three independent reviews. The workshop program also included 2 invited lectures: Database Trends and Directions: Current Challenges and Opportunities by George Feuerlicht, and Simple Mathematical Models in Biometric Image Analysis by Khalid Saeed. We wish to express our sincere thanks to all the authors who submit- ted papers, the members of the Program Committee, who reviewed them on the basis of originality, technical quality, and presentation. We are also thankful to the Organizing Committee and Amphora Research Group (ARG, http://www.cs.vsb.cz/arg/) for preparation of workshop and its proceedings as well as the Czech Society for Cybernetics and Informatics, SoSiReČR project and MIR Labs for their support of publishing this issue.
