Abstract

When natural language front-ends are introduced to database management systems, generation of quality responses have proven problematical in situations when null values arise. In our work, in which we assume the database query language is SQL, we present methods for responding with appropriate answers to null value responses. To do so we use a knowledge base based on RM/T, an extended relational model proposed by E. F. Codd. The advantages of this approach are described. To demonstrate the utility of the knowledge base, a simple knowledge base is constructed. A detailed algorithm is given to provide additional information when a null answer is returned.
你说“空”是什么意思?将零响应转化为高质量响应
当将自然语言前端引入数据库管理系统时,在出现空值的情况下,生成高质量响应已被证明是有问题的。在我们的工作中,假设数据库查询语言是SQL,我们提供了对空值响应使用适当答案进行响应的方法。为此,我们使用了一个基于RM/T的知识库,RM/T是e.f. Codd提出的一种扩展关系模型。介绍了这种方法的优点。为了演示知识库的实用性,构建了一个简单的知识库。给出了在返回空答案时提供附加信息的详细算法。
