| 摘要: |
| 介绍了一种新的基于受限汉语的数据库自然语言接口NLCQI(natural language (Chinese) query interface)的系统模型及设计框架.给出系统实现中具有特色的多栈结构的中间语言以及以关联路径搜索方法实现的中间语言向SQL转换的策略.实验表明,该系统采用的非过程化汉语查询句表达方式较自然,对汉语句型的理解、处理能力有较大的改进. |

| Abstract: |
| In this paper, model and design framework of a new database natural language (Chinese) interface technique based on the restrictive Chinese are presented. A middle language with the multi-track structure and anew policies in the transformation from middle language to SQL which implements the search approach passing relational way are described. The experimental results show that its expression is more natural and the understanding and processing capability of Chinese statements are improved evidently, because the system uses no-procedural Chinese inquiry statements. |
| Key words: natural language interface restrictive Chinese automatic segmentation middle language database model |
