基于语义近似逼近技术的多代理协作

Multi-agent Coordination Based on Semantic Approximation Technology

本体在多代理系统中起着重要的作用,它提供和定义了一个共享的语义词汇库。然而,在现实的多代理通讯的过程中,两个代理共享完全相同的语义词汇库是几乎不可能的。因为信息不完整以及本体的异构等特性,一个代理只能部分理解另外一个代理所拥有的本体内容,这使得代理间的通讯非常困难。本文就是探索利用近似逼近技术实现基于部分共享分布式本体的多代理通讯,从而实现多代理之间的协作查询。我们使用基于OWL Web本体语言的描述逻辑来描述分布式本体的近似查询技术。最终我们也开发了基于语义近似逼近方法的一个多代理协调查询系统。

Ontology plays an important role in multi-agent systems, and provides and defines a sharable semantic vocabulary. However, within multi-agent systems, it is almost impossible for multiple Web agents to completely share a same semantic vocabulary. Because of incomplete information and ontological heterogeneity, an agent can partially understand the contents of other ontologies. This makes multkagent communication difficult. In this paper, we exploit and utilize semantic approximation for implementing better multi-agent communication based on partial shared distributed ontologies, and hence achieve coordinate query among multiple agents. We use description logic based on OWL ontology language for describing ontological information. We also develope a multi-agent coordination system based on semantic approximation.
