DEACON BREADBOARD GRAMMAR.

Abstract

The DEACON (Direct English Access and Control) Breadboard is an experimental system consisting of a complete package of computer programs, syntactic/ semantic rules, and data for establishing the feasibility of basic techniques for direct English access and control of a digital computer. The programs are written in the LAP list processing language for the GE 225 computer. The grammar consists of some 200 phrase-structure type rules written in terms of special parts of speech. The parts of speech reflect the structural features of LAP, the medium used for structuring and storing the data base. The parts of speech reflect general structural properties of the data records referred to by referent words, and thus permit a generalized semantic transformation of data to be written for each syntactic rule. The semantic transformations interrelate the referents (data records) of the words in a phrase to establish a referent, or 'meaning,' for the phrase. The parts of speech used are list, entity, attribute, value, routine, number, variable, truth value, and functional word.
