COSA2 - A Cognitive System Architecture with Centralized Ontology and Specific Algorithms

In this article, we present the architectural and algorithmic details for a COgnitive System Architecture that uses a Centralized Ontology with Specific Algorithms (COSA²). COSA² is a layered intelligent agent framework on the basis of the modified Rasmussen model of human performance. It encompasses integrated algorithmic support for goal-oriented situation interpretation, dynamic planning and plan execution, as well as provisions for reactive behavior. A unique feature is the claim for an expressive, centralized knowledge representation, used by all functions to ensure consistency. The framework is being applied to different problems in the domain of uninhabited aerial vehicles. This article focuses on high level, concept-based behavior and illustrates the modeling and processing details by a simplified UAV mission management example.
