论述了基于CBR(Case Based Reasoning)模架设计的基本原理以及工作过程。阐明了模架事例的组成、表达内容、表达形式以及在事例库中的组织,并将数据库技术应用于事例数据的管理。基于特征提取技术,建立了事例库的特征索引,并给出了初步的权值。以最近邻策略为检索手段,给出了相似度计算公式。以Visual Basic语言为软件开发语言,编制了检索界面。最后给出了一个应用实例,说明系统工作过程。
The basic principle and work process of design based on CBR (Case Based Reasoning) are discussed. Clarified the composition, expression content, expression form and case organization of the mold case, and applied the database technology to the case data management. Based on the feature extraction, the feature index of the case base is established and the initial weights are given. Using nearest neighbor strategy as retrieval means, the formula of similarity calculation is given. Visual Basic language for software development language, the preparation of the search interface. Finally, an application example is given to illustrate the working process of the system.
