  • Parser for a Speech Understanding System

    This paper describes a parsing system specifically designed for spoken rather than written input. The parser is part of a project to develop a computer system for understanding speech.

  • Planning in a Hierarchy of Abstraction Spaces

    The problem solver ABSTRIPS, a modification of STRIPS, can define an abstraction of space hierarchy from the STRIPS representation of a problem domain, and it can utilize the hierarchy in solving problems. Examples of the systems performance are presented.

  • Study of Equipment Needs for Artificial Intelligence Research

    This report describes interim results of a project to specify special equipment for research in Artificial Intelligence. After surveying several potential users it was decided that there was a need for standardized equipment for robot research.

  • Hierarchical Robot Planning and Execution System

    This report describes a robot control program consisting of a hierarchically organized plan generation and execution system written in QA4 and making use of several features of that language.

  • Automated Language Processing

    The major development area involves work on question-answering systems, now coming to be called “computer understanding.” The change in terminology indicates an enrichment and elaboration of the components of such systems.

  • Bibliography on Computer Semantics

    This bibliography and topical index lists more than 200 references, almost all published since 1965, in Computer Semantics: a growing research area that lies at the boundaries of Linguistics, Psychology, and Artificial Intelligence.

  • Stereopsis Error Analysis

    The error due to image quantization in stereoscopically evaluated range is analyzed, using a simple camera model and assuming that the image planes of the two cameras are coplanar.

  • Some New Directions in Robot Problem Solving

    In this paper we describe some of the possible extensions, illustrating the discussion where possible with examples taken from the current Stanford Research Institute robot system.

  • Robots, Productivity, and Quality

    This paper proposed the development of automation technology designed to increase quality, in all its aspects, at an acceptable cost to society.

  • A Causality Representation for Enriched Robot Task Domains

    In this report we consider other families of task, such as those involving the inhibition of an action or the maintenance of the current state of its environment.

  • Efficient Calculations on Points and Lines in the Euclidean Plane

    This paper illustrates a method by which use of these functions may often be avoided, and presents explicit formulas for four basic calculations involving points and lines in two dimensions.

  • QA4 Programming Concepts

    This note presents an informal introduction to the unusual programming concepts used in the construction of such problem-solving programs.
