本文以属性文法为基础
提供了一种知识型系统的模型。模型的基本结构是带属性的树。这种模型既能体现上下文敏感的性质
又能引入启发式的知识
而且可以方便地变换成可执行的LISP程序。模型的构成方式类似于模式识别中模式的构成。最后讨论了所述方法在设计SHOCK医疗系统及地震剖面解释系统中的应用。
On the basis of attributed grammars
a model of knowledge based system is proposed. The model is basically an attributed tree-like structure. It not only has the context-sensitive properties concerned in the structure
but also can introduce the heuristic knowledge. The construction of the model is similar to the construction of the pattern in syntactic pattern recognition. The model structure may be transformed into executable LISP program. Two examples of expert system design are given to illustrate applications of the method.
