Lexical Analysis to Enhance Man/Machine Interaction: Simplifying and Improving the Creation of Software. Final Report.
Hutchins, Sandra E.
By analyzing the lexicology of natural language (English or other languages as they are commonly spoken or written), as compared to computer languages, this study explored the extent to which syntactic and semantic levels of linguistic analysis can be implemented and effectively used on microcomputers. In Phase I of the study, the Apple IIe with 64K was used for the development of demonstration programs for real-time (as fast as the user types) spelling and grammar checking to illustrate the feasibility of implementing useful programs within the constraints of a microcomputer; programs ran on an Apple II+, with 48K as well. Phase II deals with additional grammatical questions and semantic issues, again concentrating on immediate feedback and utility in the educational environment. This four-part final report comprises sections on: (1) the significance of the problem; (2) study background; (3) a summary of achievements in Phase I; and (4) the technical approach. This last section makes up the majority of the report and includes sections on: the dictionary, syntactic tags, syntactic pre-scan, tagging procedures, parsing with incomplete information, context-free grammars, user feedback, and specific accomplishments. References, sample demonstration texts, and a feature option list are appended. (THC)
