Architectures, Concepts and Technologies for Service Oriented Computing : proceedings of ACT4SOC 2010, 4th International Workshop on Architectures, Concepts and Technologies for Service Oriented Computing in cnjunction with ICSOFT 2010, Athens, Greece, July 2010

This volume contains the proceedings of the Fourth International Workshop on Architectures, Concepts and Technologies for Service Oriented Computing (ACT4SOC 2010), held on July 23 in Athens, Greece, in conjunction with the Fourth International Conference on Software and Data Technologies (ICSOFT 2010). The goal of the workshop is to focus on the fundamental and practical challenges related to SOC, to discuss what theoretical, architectural or technology foundation is needed, and how this foundation can be supported or realized by new or enhanced infrastructures, standards and/or technologies. The workshop aims at contributing to the dissemination of research results, establishment of a better understanding, and identification of new challenges related to SOC/SOA, by bringing together interested academic and industrial researchers. This year 10 papers out of 30 submissions were selected, based on a thorough review process, in which each paper was reviewed by at least 3 experts in the field. Due to the number of reviews and the professionalism of the authors, program committee members and reviewers, we are confident that all selected papers are of high quality. The selected papers are also a good illustration of the different challenges mentioned above. They have been grouped in four presentation sessions during the workshop, named "SOA applications – logistics and online advertising", "Design and analysis of service-oriented systems", "Web services composition" and "SOA applications – homecare and emergency support".
