【摘要】 分析了现有专家系统模型存在的不足,提出了一种基于面向对象技术的专家系统模型。它由知识对象和数据对象组成,对象采用类框架方法表示,系统采用全局和局部两级控制方式,全局控制采用信箱通讯,局部控制采用消息通讯,对象之间通过合作共同完成任务,从而解决了专家系统的效率和领域知识组织及使用问题。最后给出了以此模型为基础实现的证券分析专家系统实例,进一步说明了该模型的可行性和有效性。更多还原

【Abstract】 After analyzing the defects of current expert system models, an expert system model based on object-oriented technique is presented. It’s composed of knowledge objects and data objects that are represented by platform and has global and local control mecha- nism. Global control mechanism communicates by mailbox, while local control mechanism communicates by message. Objects can cooperate with each other to complete tasks. Therefore, efficiency of expert system, organization and usage of domain knowledge are solved. At last, a securities analyzing expert system sample based on this model is described to verify the feasibility and validity of this model.更多还原
