一个数控自动编程系统的自然语言接口

A NATURAL LANGUAGE INTERFACE FOR NUMERICAL-CONTROL AUTOMATIC PROGRAMMING SYSTEM

本文简要介绍了一个数控自动编程专家系统的自然语言接口的实现.该自然语言接口是以我们研制的数控自动编程专家系统为背景,运行在 SUN3/4 工作站的 UNIX 下和 IBM/AT 机的 DOS 下,用 C语言编程.该自然语言接口由词法分析、句法分析、语义语用分析、目标生成和图形仿真五个模块及相应的知识库构成.该接口能够接受数控编程系统所需的对工件的英语自然语言描述并处理一些比较简单的英语语言现象.

This paper briefly introduces the implementation of a natural language (English) interface for anumerial-control automatic programming expert system dcvclopcd by our institute.The interface is nowrunning under the UNIX on Sun 3/4 or DOS on IBM/AT and is programcd in C language.It is com-posed of lexical analytical module,syntax analytical module,scmantic-pragmatic analytical module,ob-ject gcncration module,graphic simulation module and various knowledge bascs.The interface can acceptthe description of the pieceworks necded by the cxpert system and process some simple English languagephenomena.
