Mark Weiser’s vision of computers moving out of our focus of attention and becoming oblivious devices that occur in large numbers and provide smart computing und communication services to individuals as needed is still far from being reality.This book puts the larger vision of ubiquitous computing in the context of today’s mobile and distributed computing systems and presents innovative solutions at all system layers ranging from hardware over vertical and horizontal infrastructure services and novel middleware techniques to various types of application software. Some chapters address core properties of ubiquitous applications including mobility, self-healing and self-organisation of both technical and social-technical systems. Other contributions deal with common facilities like secure e-payment or semantic web techniques and business solutions like wireless asset management or e- maintenance. Distributed systems management with self-monitoring capabilities, Internet congestion control, and novel security solutions coping with denial of service attacks against mobile agent systems and software- and hardware-based data encryption methods are further topics addressed.

Thisvolumecontainsallofthe Research-Track,Industry-TrackandDemo-Track papers that were selected for presentation at the Fifth International Conference on Service-Oriented Computing (ICSOC 2007), which was held in Vienna, A- tria, September 17–20, 2007. ICSOC 2007 followed the footsteps of four previous successful editions of the International Conference on Service-Oriented Computing that were held in Chicago,USA(2006),Amsterdam,TheNetherlands(2005),NewYorkCity,USA (2004) and Trento, Italy (2003). ICSOC is recognized as the ?agship conference for service-oriented computing research and best practices. ICSOC covers the entire spectrum from theoretical and foundational results to empirical eval- tion, as well as practical and industrial experiences. ICSOC 2007 continued this tradition while introducing several new themes to further these goals. Service-orientedcomputingbringstogetherideasandtechnologiesfrommany diverse ?elds in an evolutionary manner in order to address research challenges including service-based application modeling, service composition, discovery, - tegration, monitoring and management of services, service quality and security, methodologies for supporting service development, grid services, and novel t- ics including information as a service and service-oriented architecture (SOA) governance. To provide a balanced coverage and an equal emphasis across all aspects of service-oriented computing, ICSOC 2007’s topics were divided into seven major areas: Business Service Modeling, Service Assembly, and Service Management, addressing research issues and best practices in the primary life-cycle phases of a service, modeling, assembly, deployment, and management; SOA Runtime and Quality of Service, covering issues spanning all stages of the life-cycle; Grid Services and Service Architectures, combining grid infrastructure concepts with service-oriented computing; and Business and Economical Aspects of Services.

Welcome to the proceedings of the inaugural Symposium on Collective Intelligence (COLLIN 2010). This was the first of a new series of events that will evolve over the coming years, and we were happy to hold the event in Hagen where the idea for this symposium was born. The participants visited Hagen in April, with excellent opportunities to get rain, wind and sun. Collective intelligence denotes a phenomenon according to which the purposeful interaction between individuals creates intelligent solutions and behaviors that might not have come to existence without this concerted effort of a community. The members of such communities form a social network, typically over the Internet. They are engage with each other over a sustained period of time to develop an area of innovation through collaboration and exchange of ideas, experiences and information. Leading-edge information and communication technologies (ICT) offer ample opportunities for enabling collective intelligence. COLLIN aims to become the flagship conference in the areas collective intelligence and ICT-enabled social networking, which is attracting more and more researchers and practitioners from both academia and industry.

Collective intelligence has become an attractive subject of interest for both academia and industry. More and more conferences and workshops discuss the impact of the users‘ motivation to participate in the value creation process, the enabling role of leading-edge information and communication technologies and the need for better algorithms to deal with the growing amount of shared data. There are many interesting and challenging topics that need to be researched and discussed with respect to knowledge creation, creativity and innovation processes carried forward in the emerging communities of practice.COLLIN is on the path to become the flagship conference in the areas of collective intelligence and ICT-enabled social networking. We were delighted to again receive contributions from different parts of the world including Australia, Europe, Asia, and the United States. Encouraged by the positive response, we plan COLLIN 2012 to be held next year end of August at FernUniverstität in Hagen.In order to guarantee the quality of the event, each paper went through a doubleblind review process. The reviews concentrated on originality, quality and relevance of the paper topic to the symposium. In addition, we invited a few renowned experts in the field to contribute to the success of the symposium with outstanding papers reporting on their most recent research. Our special thanks go to the authors for submitting their papers, to the international program committee members, and to numerous reviewers who did an excellent job in guaranteeing that the papers in this volume are of very high quality.
