Knowledge Description Model for MAS Utilizing Distributed Ontology Repositories

Abstract

The rapid growth of IT technologies enables the quality of human’s daily life to be improved dramatically. Contrasting to the services in previous computing environment directed by user’s request, the services in ubiquitous computing era of new IT technology are provided through recognizing user’s intention and utilizing context-aware information suited to the user. According to the contextual information, agents need to set a dynamic goal to achieve and work collaboratively with other agents. Agents that take control over their behaviors with capability of communicating with other agents become a thrust in this up-coming computing environment. This work focuses on building ontologies, shared knowledge bases among agents, to improve semantical interoperability among agents. More attention is given to the construction and effective management of ontology repository along with its requirement and organization. Ontology agent suggested takes an initiative role to manage the repository in a distributed manner and to facilitate the use of ontology in a multi-agent environment.
