基于事例推理的知识构件的研究与实践

Research & Practice of Knowledge Component Based on CRB

基于事例的推理(CBR)是一种重要的机器学习方法,广泛应用于各类智能系统,如医疗诊断系统、客户服务系统等。本文利用XML良好的语法结构和可扩展特性来规范事例知识的表示,同时应用基于构件的软件开发模式,通过EJB技术把基于事例的推理方法构件化,形成一个可应用于分布式环境下、可复用的知识构件ComCBR。最后,一个基于J2EE的简单的网上医疗诊断系统作为ComCBR的一个应用实例而得到了设计与实现。本文旨在通过规范事例知识的表示和基于构件的开发模式这两个方向的研究来推动基于事例知识研究的应用和实践。

Case-based Reasoning （CBR） is an important machine learning method widely used in the intelligent system such as Diagnose System, CRM and so on. The case knowledge representation based on XML technology is used to uniform case knowledge representation method. And Component Based Software Development （CBSD） is used to design a component of CBR called ComCBR based on EJB technique. Finally, a simple web Diagnose System which is based on J2EE is given as an instance of ComCBR. In conclusion, this paper is trying to promote the development of the research of CBR in combining both the researches of Case knowledge presentation and CBSD.
