A Context-Aware Multi-agent Service System for Assistive Home Applications

Abstract. In this paper, we present an Ontology-based Context-aware multi-Agent Service System(OCASS) architecture to provide these context-aware services in a smart home. To model various contexts, we design Ontology which supports to share context knowledge, detect and resolve inconsistency of the knowledge. In addition, we classify context-aware services into three layers- Session, Task, Subtask- to make sure definition of service conflict problems and to solve the problems eas-ily. With our context model and the classification of service conflicts, our system supports autonomic tasks including recognizing and learning user’s formal/informal activity pattern, and resolving conflicts between services in different situations of users invisibly
