PRE (PurposefullyRestricted English) is a restricted English database query language whose implementation has addressed engineering goals, namely, habitability, interapplication transportability, performance, and use with a reliable database management system that supports large numbers of concurrent users and large databases. Habitability has not been demonstrated, but initial indications are encouraging. The other goals have clearly been achieved. The existence of the PRE system demonstrates that an explicitly "minimalist" approach to natural language processing can facilitate achievement of transportability.

During the 1970s, a number of systems providing limited English-language processing capabilities were developed to permit computer access by casual or untrained users. Our interest is in adapting and extending techniques developed for these systems, especially those used in database query systems and our own English-language programming language system (NLC), for use in office environments. This paper describes the Layered Domain Class system (LDC), a state-of-the-art natural language processor whose major goals are (1) to provide English-language retrieval capabilities for mediumsized office domains that have been stored on the computer as text-edited files, as opposed to more restrictive database structures; and (2) to eliminate the need to call in the system designer when extensions into new domains are desired, without sacrificing the depth or reliability of the interface. In this paper we (a) provide an overview of LDC, including sample inputs; (b) briefly discuss the role of each module of the system, with special attention to provisions for users to adapt the system to deal with new types of data; and (c) consider the relation of our system to other formal and natural language interfaces that are in use or under development.
