User-configurable semantic home automation

The ideas of smart home and home automation have been proposed for many years. However, when discussing homes of the future, related studies have usually focused on deploying various smart appliances (or devices) within a home environment and employing those appliances automatically by pre-defined procedures. The difficulties of supporting user-configurable automation are due to the complexity of various dynamic home environments. Moreover, within their home domains, users usually think semantically; for example, “I want to turn off all the lights on the second floor”. This paper proposes a semantic home automation system, USHAS (User-configurable Semantic Home Automation System), which adopts Web Service and WSBPEL for executing automated process; OWL and OWL-S for defining home environments and service ontology; and a self-defined markup language, SHPL (Semantic Home Process Language), for describing semantic processes.
