| 摘 要： | 针对当前研究的热点问题———界面层自然语言理解的应用,设计和研制了一个面向对象的受限汉语自然语言数据库查询系统DMNLQ。该系统针对特定的考古数字博物馆应用,提出了受限汉语的上下文无关文法,把查询语句通过定义的文法进行标注,并采用语义树的形式进行表示。系统还提出了一种中间形式语言MML对语义树进行描述,运用关联路径搜索策略解决了查询中比较复杂的表间相互联系的表述问题,从而实现了从MML到SQL语句的转换。

| Abstract: | At present,the application of natural language comprehension in the interfacial level is widely researched.Aiming at the special digital museum application,a natural language database query system(DMNLQ) based on the restrictive Chinese is introduced in this paper.The DMNLQ system adopts the OOD method and puts forward a restrictive Chinese context-irrespective grammar,in which query sentences can be labeled,and the labeled query sentences can be expressed as a semantic tree.A middle formal language(MML) is introduced to describe the semantic tree,and the associated relationship is used to solve the relations of tables and thus complete the transition from MML to SQL. |
