A Note on the Optimal Allocation of Spaces in MACLISP
(MIT Artificial Intelligence Laboratory, 1977-03-16)
This note describes a method for allocating storage among the various spaces in the MACLISP Implementation of LISP. The optimal strategy which minimizes garbage collector effort allocates free storage among the various ...
A Theory of Plans for Electronic Circuits
(MIT Artificial Intelligence Laboratory, 1977-04)
A plan for a device assigns purposes to each of the more primitive components and explains how these components interact to achieve the desired behavior of the composite device. Such an information structure is critically ...
Plan Recognition in a Programmer's Apprentice
(MIT Artificial Intelligence Laboratory, 1977-05)
Brief Statement of the Problem:
Stated most generally, the proposed research is concerned with understanding and representing the teleological structure of engineered devices. More specifically, I propose to study the ...
A History Keeping Debugging System for PLASMA
(MIT Artificial Intelligence Laboratory, 1977-05)
PLASMA (for PLAnner-like System Modeled on Actors) is a message-passing computer language based on actor semantics. Since every event in the system is the receipt of a message actor by a target actor, a complete history ...
Mapping Sentences to Case Frames
(MIT Artificial Intelligence Laboratory, 1977-03)
This paper describes a range of phenomena that a case frame system should be able to handle and proposes generalizations to capture this behavior which are formulated as a set of production-like rules. These rules allow ...
A Birthday Party Frame System
(MIT Artificial Intelligence Laboratory, 1977-02)
This paper is an experimental investigation of the utility of the MIT-AI frames system. Using this system, a birthday party planning system was written, representing the basic decisions that comprise such a plan as frames. ...
The Semantic Component of PAL: The Personal Assistant Language Understanding Program
(MIT Artificial Intelligence Laboratory, 1977-03)
This paper summarizes the design and implementation of the "semantics" module of a natural language undertanding system for the personal assistant domain. This module includes mappings to deep frames, noun phrase referencing ...
A Computational Theory of Animation
(MIT Artificial Intelligence Laboratory, 1977-04)
A system is proposed capable of generating narrative computer animation in response to a simple script. The major problem addressed is how to imbed into the system some of the knowledge that animators use when creating ...
Extracting topographic features from elevation data using contour lines
(MIT Artificial Intelligence Laboratory, 1977-05)
This paper describes a method for finding such topographical features as ridges and valleys in a given terrain. Contour lines are used to obtain the desired result.
CGOL - an Alternative External Representation For LISP users
(MIT Artificial Intelligence Laboratory, 1976-03)
Advantages of the standard external representation of LISP include its simple definition, its economical implementation and its convenient extensibility. These advantages have been gained by trading off syntactic variety ...
