2016 Computer Science and Information Systems  
In addition, a profile applied improved rule-based reasoning algorithm is integrated into this middleware to infer high-level contexts from available low-level contexts.  ...  In this paper, we proposed a middleware architecture for a context-aware system in smart home environment. Here, the context is modeled based on ontology using Web Ontology Language (OWL).  ...  If a match is not found, the reasoning engine checks whether or not the high-level context is still valid. The user status is changed to none, when the condition for the high-level context is failed.  ...
