中文摘要:

以“问题-原因-解决方案”来表达的这类经验性知识,常用“大概”或“很可能”等感性词语修饰,具有模糊性和不确定性的特点,且解决方案与问题和原因高度关联,该特点适合用产生式规则来表示。为便于计算机处理.产生式规则往往由计算机能识别的某种编码组成,而这类编码用户无法解读,需将其“翻译”成人类易于理解的自然语言。文中探讨了如何表示这类经验性知识,提出了一种模板解释方法,采用MVC(Model—View—Controller,MVC)架构、基于VS2005+SQL Server2000平台实现了该解释器。该解释器已在某模具厂的改模知识归纳系统中应用且取得了良好的效果。

英文摘要:

The experiential knowledge expressed by the way of "problems-causes-solutions" takes on the characteristics of fuzziness and uncertainty that are caused by the use of the perceptual words such as "probably", "likely" and so on. The solution of it is highly related to the causes, which suits the production rule. For the sake of processing in computer, production rule is usually constituted of certain codes recognizable by the computer but not for users, so these rules should be "translated" into a language understandable for human beings. Aiming to this goal, this article first discusses the way how to express the experiential knowledge, and then puts forward a interpreter on the basis of the template, at last points out how to realize the interpreter on the basis of MVC (Model - View- Controller) framework and the platform of VS2005 + SQL server2000. This interpreter has now been applied in a die shop and achieved a satisfactory result.
