Peer reviewedYannakoudakis, Emmanuel J.; Attar-Bashi, Hussain A. – Journal of Documentation, 1989
Describes a model that displays structures necessary to map between the conceptual and external levels in database management systems, using an algorithm that maps the syntactic representations of tuples onto semantic representations. A technique for translating tuples into natural language sentences is introduced, and a system implemented in…
