Yu Zheng · Journal of Kunming University of Science and Technology · 2004
Database query is implemented by SQL (Structrued Query Language) in general. Yet it is difficult to master SQL for the general users. In order to improve the flexibility of man-machine interface, database query using natural language is involved. Question sentences must be transformed into SQL of database in the transaction. The interface architecture of the database query using naturual language is introduced. And then the process including sentence analysis of natural language, formalization analysis of query sentence, generation of middle query language and algorithm of SQL transformation is introduced in detail by taking the domain of the house as an example. This query interface is proved better performance in restricted domain by the experiments.
