A Self-organising Agent Assistant System

Abstract

To resolve the problem of agent tending to be helpless when performing tasks in the Internet in which is full of uncertain factors, this paper proposes a hierarchy-like agent assistant service framework that provides mediate services in agent society. This assistance services system is divided into three layers: the bottom is a description layer, which describes agent services and domain ontology by self-defined Ontology Based Knowledge Representation Language (OKRL); the middle is a support layer, which provides management mechanism to organize middle agent nodes and information repository of assistant services for upper layer; the top is assistant services layer, which provides services for registration, advisement and matchmaking of agent services. The growth mechanism and joint matchmaking process of middle agents, which realizes self-organising characteristic for agent assistant system, are also discussed in this paper. Finally, this paper gives evaluation and conclusion.
