面向对象工程数据库的自然语言查询

Natural Language Query for Object-oriented Engineering Database

通过面向对象的分析,将面向对象的查询转换成关系语义的查询。针对自然语言查询的特点,采用 Montangue 语义法进行语义分析。提出了描述自然语言查询语义的类关系代数表达式以及类关系代数表达式的确定化方法。该自然语言查询接口具有容易修改,通用性好的优点。

In this paper, we translate the guery for object into the one for relation according to the object concept, use Montangue's semantic approach to analyse Chinese semantics, propose the concept of resemble relational algebra and the filling up nethods. This general interface of Chi- nese natural language query for database is easy to modify and transplant.
