A program structure based on recently developed techniques for operating system simulation has the required flexibility for use as a speech synthesis algorithm research framework. This program makes synthesis possible with less rigid time and frequency-component structure than simpler schemes. It also meets real-time operation and memory-size…

A collection of computer programs to do chemical information retrieval are described in terms of the interactions between the computer and the chemist. In interacting with the computer, the chemist can graphically specify two-dimensional structures as queries and view structures as search results. (18 references) (Author/NH)

Outlines a new approach to the design of learning machines which can be taught how to solve problems in industrial automation and other fields; and describes PURR-PUSS, a working system embodying this approach. The two key features of the system are "multiple context" and "novelty"; their contribution to the teachability of…

Describes the structure of MYCIN, a computer-based consultation system designed to assist physicians in the diagnosis of and therapy selection for patients with bacterial infections, and an explanation system which can answer simple English questions in order to justify its advice or educate the user. (Author/VT)

This report describes the current version of the Why System, a script-based Socratic tutor which uses tutoring strategies formulated as production rules. The current system is capable of carrying on a dialogue about the factors influencing rainfall by presenting different cases to the student, asking for predictions, probing for relevant factors,…

Requirements are discussed for an information retrieval language that enables users to employ natural language sentences in interaction with computer-stored files. Anticipated modes of operation of the system are outlined. These are: the search mode, the dictionary mode, the tables mode, and the statistical mode. Analysis of sample sentences…

This paper is concerned with providing automatically generated online explanations to the user of a user interface or "tool" about what the interface can and cannot do, and what parameters or options are available or required with a given command. The COUSIN interface system, developed at Carnegie-Mellon, supplies a cooperative…

Requirements for a desirable authoring system are reviewed and a proposal for an interrogative authoring system presented. (Author)

This report consists of two papers on MENUNIX, an experimental interface to the approximately 300 programs and files available on the Berkeley UNIX 4.0 version of the UNIX operating system. The first paper discusses some of the psychological concerns involved in the design of MENUNIX; the second is a tutorial user manual for MENUNIX, in which the…

Model building techniques from Artifical Intelligence and Information-Processing Psychology are applied to human-computer interface tasks to evaluate existing interfaces and suggest new and better ones. The model is in the form of an augmented transition network (ATN) grammar which is built by applying grammar induction heuristics on a sequential…

The Maryland Refutation Proof Procedure System (MRPPS) is an interactive experimental system intended for studying deductive search methods. Although the work is oriented towards question-answering, MRPPS provides a general problem solving capability. There are three major components within MRPPS. These are: (1) an inference system, (2) a search…

Presents a justification of the belief that science and art can be successfully combined. The computer's merits are viewed as a potential modelbuilder for the formalization of aesthetic concepts. The rest of the paper details recent and current research on such uses of the machine. (VT)

Proposes extensions to PASCAL that provide for programing man-computer dialogues. An interactive dialogue application program is viewed as a sequence of frames and separate computational steps. PASCAL extensions allow the description of the items of information in each frame and the inclusion of behavior rules specifying the interactive dialogue.…

A computer was used to help a man who stuttered severely most of his 37 years. The criterion based treatment used a specifically designed program (Speech Flow Acquisition Program) to train him to speak smoothly. (SEW)

Paper describes a method of analysing information based on theories about the way in which human beings tackle this problem. (Author)
