A Novel Approach for Distributed Information Sharing Based on Ontology Context Immigration

In recent years, some strategies for distributed information sharing among multi-agents have been proposed, and a system relevant to each strategy had been constructed. However, most of them depend upon a centralized architecture. This paper presents an approach for distributed information sharing based on ontology context immigration (OCI) and a distributed information sharing system (DISS) constructed according to it. The method proposed can route automatically and download selectively useful information (ontology context) from remote agents for local queries. Evaluation results indicate that DISS has the same search capability of a centralized system and it can reduce the response time remarkably. Most of all, DISS can avoid successfully the problem of consistency maintaining that troubled by a centralized architecture.
