Cloud computing has been evolved as a key computing platform for sharing resources and services. People should have a relatively convenient environment and life for handling home-appliances. This study designs and develops a Web 2.0 Service Platform (WSP) for DPWS-based Home-appliances in the Cloud environment, which is composed of mobile users, home appliances and the cloud environment. WSP automatically records and observes user's behaviors to adapt related home-appliances based on the ontology technique. A mobile user can use a smart phone to control and handle home-appliances through Web2.0 Blog-based interfaces. Finally, WSP can be an inference model for researchers when developing home-appliance controllers in the future.
