| 摘要: |
| 冗余性控制是研究知识库组织、管理和维护中的一个问题．本文通过对智能型机译系统中规则知识表示方法的分析，提出了将冗余规则划分为显式冗余规则和隐式冗余规则分别予以处理的思想，给出了显式冗余规则的判别算法和部分隐式冗余规则的检测标准，并提出了控制机译系统规则库冗余性的基本原则. |

| Abstract: |
| Redundancy control is an important aspect in knowledge organization，management and maintenance．According to the characteristics of SC—grammar and ma—chine translation system，this paper presents a new idea that divides redundant rules intotwo kinds：obvious redundant rules and hidden redundant rules．The paper gives an algo—rithm for finding obvious redundant rules and discusses in detail the basic strategies that rule out some hidden redundant rules reasonably．Some basic principles to control redun—dancy of rule base are given also． |
| Key words: Machine translation rule base knowledge base SC grammar redundancy |
