The XPRT Description System
(MIT Artificial Intelligence Laboratory, 1979-01)
This paper introduces a frame-based description language and studies methods for reasoning about problems using knowledge expressed in the language.
The system is based on the metaphor of a society of communicating experts ...
Building English Explanations from Function Descriptions
(MIT Artificial Intelligence Laboratory, 1979-04)
An explanatory component is an important ingredient in any complex AI system. A simple generative scheme to build descriptive phrases from Lisp function calls can produce respectable explanations if explanation generators ...
Design of LISP-based Processors, or SCHEME: A Dielectric LISP, or Finite Memories Considered Harmful, or LAMBDA: The Ultimate Opcode
(1979-03-01)
We present a design for a class of computers whose 'instruction sets' are based on LISP. LISP, like traditional stored-program machine languages and unlike most high-level languages, conceptually stores programs and data ...
Learning and Reasoning by Analogy: The Details
(1979-04-01)
We use analogy when we say something is a Cinderella story and when we learn about resistors by thinking about water pipes. We also use analogy when we learn subjects like Economics, Medicine and Law. This paper ...
A Truth Maintenance System
(1979-06-01)
To choose their actions, reasoning programs must be able to make assumptions and subsequently revise their beliefs when discoveries contradict these assumptions. The Truth Maintenance System (TMS) is a problem solver ...
K-Lines: A Theory of Memory
(1979-06-01)
Most theories of memory suggest that when we learn or memorize something, some "representation" of that something is constructed, stored and later retrieved. This raises questions like: How is information represented? ...
Director Guide
(1979-12-01)
Director is a programming language designed for dynamic graphics, artificial intelligence, and use by computer-naﶥ people. It is based upon the actor or object oriented approach to programming and resembles Act 1 ...
The Evaluation and Cultivation of Spatial and Linguistic Abilities in Individuals with Cerebral Palsy
(1979-10-01)
The work of the Cerebral Palsy project (members: Seymour Papert, Sylvia Weir, Jose Valente and Gary Drescher) over the past eighteen months is summarized, and the next phase of activity is outlined. The issues to be ...
Using Parallel Processing for Problem Solving
(1979-12-01)
Parallel processing as a conceptual aid in the design of programs for problem solving applications is developed. A pattern directed invocation language know as Ether is introduced. Ether embodies tow notions in language ...
Numerical Shape from Shading and Occluding Contours in a Single View
(1979-11-01)
An iterative method of using occluding boundary information is proposed to compute surface slope from shading. We use a stereographic space rather than the more commonly used gradient space in order to express occluding ...
