Context Modeling for Active Assistance

Context awareness is the key to any active assistance system. The Human Behavior Monitoring and Support project (HBMS) applies a multilevel context modeling approach, aiming to achieve context readability, reuse, adaptability and interoperability. The HBMS-System is the resulting active assistance system, which is multiply deployable in different domains to support the behavior of users in situations referring to the user’s own episodic knowledge. The HBMSSystem represents and preserves behavior and context knowledge in form of a Human Cognitive Model (HCM) expressed in a domain specific modeling language, called HCM-L. The first version of the HCM-L particularly focused on user behavior modeling. However, evaluations of first use case scenarios made clear that structural context elements like environment, spatiality and personal and social context have to be dealt in more detail. This paper summarizes the requirements for an extended HBMS context model and presents the advanced HCM-L at meta-level M2 also by giving examples on level M1.
