The Context-aware approach has proven to be an effective technique for software model-checking verification. It focuses on the explicit modelling of environment as one or more contexts. In this area, specifying precise requirement is a challenged task for engineer since often environmental conditions lack of precision. A DSL, called CDL, has been proposed to facilitate the specification of requirement and context. However, such language is still low-level and error prone, difficult to grasp on complex models and assessment about its usability is still mitigated. In this paper, we propose a high level formalism of CDL to facilitate specifying contexts based on interaction overview diagrams that orchestrate activity diagrams automatically transformed from textual use cases. Our approach highlights the boundaries between the system and its environment. It is qualified as model checking context-aware that aims to reduce the semantic gap between informal and formal requirements, hence the objective is to assist and encourage engineers to put sufficient details to accomplish effectively the specification process.
