  abstract     = {{One of the central research challenges in the Internet of Things and Ubiquitous Computing domains is how users can be enabled to "program" their personal and industrial smart environments by combining services that are provided by devices around them. We present a service composition system that enables the goal-driven configuration of smart environments for end users by combining semantic metadata and reasoning with a visual modeling tool. In contrast to process-driven approaches where service mashups are statically defined, we make use of embedded semantic API descriptions to dynamically create mashups that fulfill the user's goal. The main advantage of our system is its high degree of flexibility, as service mashups can adapt to dynamic environments and are fault-tolerant with respect to individual services becoming unavailable. To support users in expressing their goals, we integrated a visual programming tool with our system that allows to model the desired state of a smart environment graphically, thereby hiding the technicalities of the underlying semantics. Possible applications of the presented system include the management of smart homes to increase individual well-being, and reconfigurations of smart environments, for instance in the industrial automation or healthcare domains. 

Note to Practitioners-Machine tooling times are an important factor especially when producing small batch sizes. Our approach holds the potential to have manufacturing lines reconfigure themselves at runtime, based on descriptions of the functionality of individual devices. It can even consider properties that influence the process indirectly ("nonfunctional"), such as the time or monetary cost of a process. We additionally implemented a system that makes these rather complex descriptions understandable for nonspecialists. In this paper, we describe use cases from the home automation and future manufacturing domains.}},
