The Structured Planning and Debugging Editor (SPADE) is a new kind of interactive programming environment in which computer programs are generated by explicitly articulating planning decisions. The design of SPADE is based upon the development of a grammar of plans from a taxonomy of basic planning techniques. The utility of this approach to…

This report addresses the problems of using natural language (English) as the communication language for advanced computer-based instructional systems. The instructional environment places requirements on a natural language understanding system that exceed the capabilities of all existing systems, including: (1) efficiency, (2) habitability, (3)…

SESSION 63 OF THE 1967 INSTITUTE OF ELECTRICAL AND ELECTRONIC ENGINEERS INTERNATIONAL CONVENTION BROUGHT TOGETHER SEVEN DISTINGUISHED MEN WORKING IN FIELDS RELEVANT TO LANGUAGE. THEIR TOPICS INCLUDED ORIGIN AND EVOLUTION OF SPEECH AND LANGUAGE, LANGUAGE AND CULTURE, MAN'S PHYSIOLOGICAL MECHANISMS FOR SPEECH, LINGUISTICS, AND TECHNOLOGY AND…

THE AUTHOR RECOUNTS THE RISE IN IMPORTANCE OF MACHINE TRANSLATION, WHICH TOGETHER WITH LANGUAGE LEARNING AND TEACHING COMPRISE THE MAJOR FIELDS OF APPLIED LINGUISTICS. MUCH OF THE RECENT THEORETICAL WORK ON LANGUAGE DEALS WITH THE PROBLEM OF THE RELATIONSHIP BETWEEN THE SURFACE SYNTACTIC STRUCTURE OF LANGUAGE AND THE UNDERLYING STRUCTURE. THE…

This report describes several of the design decisions underlying ACT, a production system model of human cognition. ACT can be considered a high level computer programming language as well as a theory of the cognitive mechanisms underlying human information processing. ACT design decisions were based on both psychological and artificial…

AUTOQUEST is a computer aid to independent study. It presents ordinary text to a student at a computer terminal, a paragraph at a time. Using a pattern-matching approach, the system generates a question based on one of the sentences of the text and grades the student's answer. If the student's answer does not match the words of the text, the…

Research was done to develop techniques to facilitate natural communication between computers and people, other computers, and real time devices. The work was divided into tasks covering representation of semantic information, special purpose languages, real-time input-output, pattern recognition, and time-sharing research and modeling.

This is the final scientific research report for the research in programing at Carnegie-Mellon University during 1968-1970. Three team programing efforts during the past two years have been the development of (1) BLISS--a system building language on the PDP-10 computer, (2) LC2--a conversational system on the IBM/360, and L*--a system building…

The final report of a two-year study concerned with the digital-computer processing of graphical data. Five separate investigations carried out under this study are described briefly, and a detailed bibliography, complete with abstracts, is included in which are listed the technical papers and reports published during the period of this program.…

This report describes for the potential user a set of procedures for processing textual materials on-line. In this preliminary model an information analyst can scan through messages, reports, and other documents on a display scope and select relevant facts, which are processed linguistically and then stored in the computer in the form of logical…

This dissertation presents a pragmatic interpreter/translator called Real English to serve as a natural language man-machine communication interface in a multi-mode on-line information retrieval system. This multi-mode feature affords the user a library-like searching tool by giving him access to a dictionary, lexicon, thesaurus, synonym table,…

Section I of this report discusses the theoretical issues relating to the development of syntax recognition routines based on psychological models of human speech recognition and reviews the relevant psychological literature. The research reported deals with attempts to relate various syntactic variables to measures of the perceptual complexity of…

The augmented transition network described in this report was developed in the course of work in semantic interpretation in the context of a computer system which answers English questions. In order to provide mechanical input for the semantic interpreter, a parsing program based on the notion of a "recursive transition network grammar" was…

This document comprises the first part of the section of the Noun Reference Dictionary concerned with nouns derived from verb roots. See AL 002 270 for Part II. The format of this section is the same as that described in AL 002 267 for the pure nominal section of the dictionary. Roots are indicated. For other related documents, see ED 019 668, AL…

This document comprises the second part of the section of the Noun Reference Dictionary concerned with nouns derived from verb roots. See AL 002 269 for the first part, ED 019 668 and AL 002 296 for a description of the project, and AL 002 267 and AL 002 268 for the section of the dictionary dealing with pure nominals. (DO)
