The KnowLang approach to self-adaptation

Self-adaptive systems autonomously monitor their behavior and eventually modify that behavior according to changes in the operational environment or in the system itself. In this entry, we present an approach to implementing self-adaptation capabilities with KnowLang, a special framework for knowledge representation and reasoning. KnowLang provides for a special knowledge context and a special reasoner operating in that context. The approach is formal and demonstrates how knowledge representation and reasoning help to establish the vital connection between knowledge, perception, and actions that realize selfadaptive behavior. Knowledge is used against the perception of the world to generate appropriate actions in compliance with some set of goals and beliefs.
