Customizable active situation awareness framework based on meta-process in ontology

Abstract

Situation awareness aims to simulate human's awareness. There have been several frameworks for the situation awareness. However, the existing frameworks have some problems for reasoning relations between multiple domain situations. The framework provides an entire sequence for situation awareness for the domain, but not how to streamline the sequence at different domains. We created rules to infer higher level's situation awareness on time and space for streamlining the aware sequence, devised meta event ontology for defining terms and process between different domains. There are common concepts (e.g. actor, object, relation) and properties (e.g. time and space) in almost situations, crossing multiple domains. These concepts and properties enable to infer relations between situations at different domains. Our meta-event ontology and rules are designed for abstraction of inference concept and process. Customizable active situation awareness (ASA) framework takes these concepts in the existing ASA framework then it contributes to situation awareness for multiple domains. We explained the ontologies and principles of the rules and a prototype of the customizable ASA framework.
