A framework is proposed for developing a portable natural language interface to large data bases. A discussion of problems arising from portability leads to the identification of a key a concept of the framework: a conceptual schema for representing a user’s model of the domain as distinct from the data base schema. The notions of conceptual completeness and linguistic coverage are shown to be natural consequences of this framework. An implementation of the framework, called D-LADDER, is presented, and some preliminary performance results reported.
