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.
The Incremental Garbage Collection of Processes
(MIT Artificial Intelligence Laboratory, 1977-06)
This paper investigates some problems associated with an argument evaluation order that we call "future" order, which is different from both call-by-name and call-by-value. In call-by-future, each formal parameter of a ...
AMORD: A Deductive Procedure System
(MIT Artificial Intelligence Laboratory, 1977-08)
We have implemented an interpreter for a rule-based system, AMORD, based on a non-chronological control structure and a system of automatically maintained data-dependencies. The purpose of this paper is tutorial. We wish ...
A Method, Based on Plans, for Understanding How a Loop Implements a Computation
(MIT Artificial Intelligence Laboratory, 1977-07)
The plan method analyzes the structure of a program. The plan which results from applying the method represents this structure by specifying how the parts of the program interact. This paper demonstrates the utility of the ...
Rational Arithmetic For Mini-Computers
(MIT Artificial Intelligence Laboratory, 1977-09)
A representation for numbers using two computer words is discussed, where the value represented is the ratio of the corresponding integers. This allows for better dynamic range and relative accuracy than single-precision ...
Dynamics of a Three Degree of Freedom Kinematic Chain
(MIT Artificial Intelligence Laboratory, 1977-10)
In order to be able to design a control system for high-speed control of mechanical manipulators, it is necessary to understand properly their dynamics. Here we present an analysis of a detailed model of a three-link device ...
