Service providers and manufacturers released their services and functions by open APIs in the Internet of Things (IoT) service environment. And, user wants to create their own IoT service that satisfies the diverse goals in their daily lives. But IoT service creation is difficult to a non-technical user, because the existing service creation environment is required programmable ability and analytical...
Context information processing is important to provide the Internet of Things (IoT) services. To do this, we use the ontology that is one of semantic technologies. In this paper, we design the ontology to process context information and provide context service. So, we propose the Generic Ontology Models (GOMs) for context service. Moreover, through the intelligent alarm service as the use case, we...
The existing service mash-up environment enables user to create context aware services. It is able to build services by recombining ready-made building blocks and connection operations. But a non-technical user is difficult to create context aware service. Because, they don't know principles of service offering (e.g., service platform architecture, concept of ontology, criteria of context, required...
