A natural language system and its users

Describes the results of an ICL-internal project to produce a natural enquiry language system (NEL) by adding a PROLOG front-end to Querymaster, the standard ICL program for querying information stored in a database. Querymaster runs under VME on the ICL 2900 series and Series 39 computers. It provides access to various types of database including IDMS and conventional files, using CAFS (content addressable file store) high-speed facilities where appropriate. The user expresses his questions to Querymaster in an easy to use computer language.<
