An Intermediate Language for Semantic Exceptions in Context-Aware Systems

Semantic exceptions mean undesirable contexts with respect to application semantics in context aware systems. Description of such semantic exceptions is based on regular expressions, which entails high complexity to detect exceptions. In this paper we devise an intermediate language for semantic exceptions of context aware applications. By bridging the gap between high level programming languages and event stream processing engines, this language is expected to mitigate the complexity and to provide opportunities to optimize exception detection process.
