Detailing Reviews and Ratings for Trust-Enhanced Composition

Book excerpt: 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.
