Overview of A Chinese Natural Language Interface to Databases: NChiql
Xiaofeng Meng, Shan Wang, Kam‐Fai Wong · International Journal of Computer Processing Of Languages · 2001
Numerous natural language interface to databases (NLIDBs) which were developed in the mid-1980s demonstrated impressive characteristics in certain application areas. But NLIDBs did not gain the expected commercial acceptance. We argue that this was due to two major reasons, i.e., limited portability and poor usability. This paper describes the design and implementation of NChiql, a Chinese natural language interface to databases. We define the Semantic Conceptual Model (SCM) for the domain specific knowledge representations and extraction strategies. SCM depicts database semantics and is used to formulate natural language queries. Further, we present a novel method to process the Chinese natural language queries. Experiments show that NChiql has good usability and high correctness.
