Discourse Structure
(MIT Artificial Intelligence Laboratory, 1976-08-17)
An essential step in understanding connected discourse is the ability to link the meanings of successive sentences together. Given a growing database to which new sentence meanings must be linked, which out of many possible ...
Structured Planning and Debugging: A Linguistic Approach to Problem Solving
(MIT Artificial Intelligence Laboratory, 1976-06-08)
A structured approach to planning and debugging is obtained by using an Augmented Transition Network (ATN) to model the problem solving process. This proves to be a perspicuous representation for planning concepts including ...
On the Representation and Use of Semantic Categories: A Survey and Prospectus
(MIT Artificial Intelligence Laboratory, 1976-05)
This paper is intended as a brief introduction to several issues concerning semantic categories. These are the everyday, factual groupings of world knowledge according to some similarity in characteristics. Some psychological ...
Two Simple Algorithms For Displaying Orthographic Projections of Surfaces
(MIT Artificial Intelligence Laboratory, 1976-08)
Two simple algorithms are described for displaying orthographic projections of surfaces. The first, called RELIEF-PLOT, produces a three-dimensional plot of a surface z = f(x,y). The second, called SHADED-IMAGE, adds ...
Hand Eye Coordination
(MIT Artificial Intelligence Laboratory, 1976-07)
This paper describes a simple method of converting visual coordinates to arm coordinates which does not require knowledge of the position of the camera(s). Comparisons are made to other methods and two camera, three ...
An Actor-Based Computer Animation Language
(MIT Artificial Intelligence Laboratory, 1976-02)
This paper reproduces an appendix of a doctoral thesis proposal that describes a language based on actor semantics designed especially for animation. The system described herein is built upon MacLisp and is also compatible ...
Digital Control of a Six-Axis Manipulator
(MIT Artificial Intelligence Laboratory, 1976-08)
This paper describes a scheme for providing low-level control of a multi-link serial manipulator. The goal was to achieve adaptive behavior without making assumptions about the environment.
Computer Detection of Bent Fingers in Lead Bonding Frames
(MIT Artificial Intelligence Laboratory, 1976-01)
In the production of logic circuits in dual inline packages, various tedious assembly line tasks are performed by human operators using microscopes or television enlargements. One boring and difficult task is the detection ...
A Knowledge-Based Computer Animation System
(MIT Artificial Intelligence Laboratory, 1976-02)
This paper reproduces part of a doctoral thesis proposal describing the design of a system capable of generating animated drawings in response to a simple story. The representation and interaction of the various sources ...
Knowledge Driven Recognition of the Human Body
(MIT Artificial Intelligence Laboratory, 1976-01)
This paper shows how a good internal model of the subject viewed aids in the visual recognition and following of key parts. The role of knowledge driven top-down tools and methods is shown by recognizing a series of human ...
