KDA: a knowledge-based database assistant with a query guiding facility
Xu Wu, T. Ichikawa · IEEE Transactions on Knowledge and Data Engineering · 1992
A knowledge-based database assistant (KDA) which integrates a natural language query system with a skeleton-based query guiding facility is provided. When a user works with the KDA natural language query system, the query guiding facility can supply several kinds of skeletons to guide users in performing database retrieval tasks. A semantic network model, S-Net, is introduced to represent the knowledge for natural language query processing and skeleton generation. Methods for implementing the system are discussed.>
