Modeling Semantic Memory: Effects of Presenting Semantic Information in Different Modalities
(1978-04-01)
How is semantic information from different modalities integrated and stored? If related ideas are encountered in French and English, or in pictures and sentences, is the result a single representation in memory or two ...
Assessment and Documentation of a Children's Computer Laboratory
(1977-09-01)
This research will thoroughly document the experiences of a small number of 5th grade children in an elementary school computer laboratory, using LOGO, an advanced computer language designed for children. Four groups ...
Shaded Perspective Images of Terrain
(1978-03-01)
In order to perform image analysis, one must have a thorough understanding of how images are formed. This memo presents an algorithm that produces shaded perspective images of terrain as a vehicle to understanding the ...
A Glimpse of Truth Maintenance
(1978-02-01)
Many procedurally-oriented problem solving systems can be viewed as performing a mixture of computation and deduction, with much of the computation serving to decide what deductions should be made. This results in ...
Programming Viewed as an Engineering Activity
(1978-01-01)
It is profitable to view the process of writing programs as an engineering activity. A program is a deliberately contrived mechanism constructed from parts whose behaviors are combined to produce the behavior of the ...
A Comparison of PARSIFAL with Augmented Transition Networks
(1978-03-01)
This paper compares Marcus' parser, PARSIFAL with Woods' Augmented Transition Network (ATN) parser. In particular, the paper examines the two parsers in light of Marcus' Determinism Hypothesis. An overview of each ...
A Glimpse of Truth Maintenance
(1978-11-01)
To choose their actions, reasoning programs must be able to draw conclusions from limited information and subsequently revise their beliefs when discoveries invalidate previous assumptions. A truth maintenance system ...
LANDSAT MSS Coordinate Transformations
(1978-02-01)
A number of image analysis tasks require the registration of a surface model with an image. In the case of satellite images, the surface model may be a map or digital terrain model in the form of surface elevations on ...
Learning Disjunctive Concepts From Examples
(1979-09-01)
This work proposes a theory for machine learning of disjunctive concepts. The paradigm followed is one of teaching and testing, where the teaching is accomplished by presenting a sequence of positive and negative ...
Instrumental With and the Control Relation in English
(1979-11-01)
This paper explores the nature of the underlying representation of a sentence, that representation formulated to make explicit the semantic structure of a sentence as a description of an event. It argues that the ...
