This book is an attempt to bring closer the greater vision of the development of Social Informatics. Social Informatics can be de?ned as a discipline of informatics that studies how information systems can realize social goals, use social concepts, or become sources of information about social phenomena. All of these research directions are present in this book: fairness is a social goal; trust is a social concept; and much of this book bases on the study of traces of Internet auctions (used also to drive social simulations) that are a rich source of information about social phenomena. The book has been written for an audience of graduate students working in the area of informatics and the social sciences, in an attempt to bridge the gap between the two disciplines. Because of this, the book avoids the use of excessive mathematical formalism, especially in Chapter 2 that attempts to summarize the theoretical basis of the two disciplines of trust and fa- ness management. Readers are usually directed to quoted literature for the purpose of studying mathematical proofs of the cited theorems.

Addresses the need for peer-to-peer computing and grid paradigms in delivering efficient service-oriented computing.

The Internet has developed from an information platform to a business platform. Fostered by the Internet of Things, the Internet of Services is the "new economy" in the Internet. Business providers compose Internet services offered by other parties to value-added, composite services. A new business model has evolved from the possibility to combine independent services to new ones. This book contributes new methods and approaches to stakeholders in the setting of composite services in the Internet of Services. Providers and customers often encounter situations in which information on the quality of offered services is scarce and subject to uncertainty. Deciding for one service or the other includes the possibility of unwittingly paying for a service of low quality while another, better, service is readily available. Distinguishing between good and bad services is both difficult and important for successful business activities in this setting. While trust is a well-known concept in human interaction, it has long been neglected in technical settings. Since the introduction of computational trust, researchers are working on making mechanisms of human trust usable in technical settings. This book applies and evolves computational trust for the application in composite service settings.

This book treats the computational use of social concepts as the focal point for the realisation of a novel class of socio-technical systems, comprising smart grids, public display environments, and grid computing. These systems are composed of technical and human constituents that interact with each other in an open environment. Heterogeneity, large scale, and uncertainty in the behaviour of the constituents and the environment are the rule rather than the exception. Ensuring the trustworthiness of such systems allows their technical constituents to interact with each other in a reliable, secure, and predictable way while their human users are able to understand and control them. "Trustworthy Open Self-Organising Systems" contains a wealth of knowledge, from trustworthy self-organisation mechanisms, to trust models, methods to measure a user's trust in a system, a discussion of social concepts beyond trust, and insights into the impact open self-organising systems will have on society.

This book consists of twelve different contributions that reflect several aspects of OC research. Therefore, we introduced four major categories summarizing the contents of the contributions as well as describing the different aspects of OC research in general: (1) design and architectures, (2) trustworthiness, (3) self-learning, and (4) self-x properties.
