Frame-based Text Processing
(1977-11-01)
This paper presents an overview of a theory of discourse structure, and discusses a model for assimilating text into a frame-based data structure. The model has been applied to the analysis of news articles. The theory ...
Teacher's Guide for Computational Models of Animal Behavior
(1977-04-01)
This is an experimental curriculum unit which suggests how the computational perspective can be integrated into a subject such as elementary school biology. In order to illustrate the interplay of computer and non-computer ...
Modelling Distributed Systems
(1977-06-01)
Distributed systems are multi-processor information processing systems which do not rely on the central shared memory for communication. This paper presents ideas and techniques in modelling distributed systems and ...
Plain Talk About Neurodevelopmental Epistemology
(1977-06-01)
This paper is based on a theory being devloped in collaboration with Seymour Papert in which we view the mind as an organized society of intercommunicating "agents". Each such agent is, by itself, very simple. The ...
The Incremental Garbage Collection Processes
(1977-12-01)
This paper investigates some problems associated with an expression evaluation order that we call "future" order, which is different from call-by-name, call-by-value, and call-by-need. In future order evaluation, an ...
A Theory of Human Stereo Vision
(1977-11-01)
An algorithm is proposed for solving the stereoscopic matching problem. The algorithm consists of five steps: 1.) Each image is filtered with bar masks of four sizes that vary with eccentricity; the equivalent filters ...
Levels of Complexity in Discourse for Reference Disambiguation and Speech Act Interpretation
(1977-05-01)
This paper presents a discussion of means of describing the discourse and its components which makes speech act interpretation and reference disambiguation possible with minimal search of the knowledge in the database. ...
Representing Visual Information
(1977-05-01)
Vision is the construction of efficient symbolic descriptions from images of the world. An important aspect of vision is the choice of representations for the different kinds of information in a visual scene. In the ...
Control and Learning by the State Space Model: Experimental Findings
(1977-04-01)
This is the second of a two part presentation of a model for motor control and learning. The model was implemented using a small computer and the MIT -Scheinman manipulator. Experiments were conducted which demonstrate ...
Electrical Design: A Problem for Artificial Intelligence Research
(1977-06-01)
This report outlines the problem of intelligent failure recovery in a problem-solver for electrical design. We want our problem solver to learn as much as it can from its mistakes. Thus we cast the engineering design ...
