Jokes and the Logic of the Cognitive Unconscious
(1980-11-01)
Freud's theory of jokes explains how they overcome the mental "censors" that make it hard for us to think "forbidden" thoughts. But his theory did not work so well for humorous nonsense as for other comical subjects. ...
Flavors: Message Passing in the Lisp Machine
(1980-11-01)
The object oriented programming style used in the Smalltalk and Actor languages is available in Lisp Machine Lisp, and used by the Lisp Machine software system. It is used to perform generic operations on objects. Part ...
The Curve of Least Energy
(1981-01-01)
Here we search for the curve which has the smallest integral of the square of curvature, while passing through two given points with given orientation. This is the true shape of a spline used in lofting. In computer-aided ...
Destructive Reordering of CDR-Coded Lists
(1980-08-01)
Linked list structures can be compactly represented by encoding the CDR ("next") pointer in a two-bit field and linearizing list structures as much as possible. This "CDR-coding" technique can save up to 50% on storage ...
A Multiprocessor Architecture Using Modular Arithmetic for Very High Precision Computation
(1989-04-01)
We outline a multiprocessor architecture that uses modular arithmetic to implement numerical computation with 900 bits of intermediate precision. A proposed prototype, to be implemented with off-the-shelf parts, will ...
Lexical Conceptual Structure and Generation in Machine Translation
(1989-06-01)
This report introduces an implemented scheme for generating target- language sentences using a compositional representation of meaning called lexical conceptual structure. Lexical conceptual structure facilitates two crucial ...
Conceptual Basis of the Lexicon in Machine Translation
(1989-08-01)
This report describes the organization and content of lexical information required for the task of machine translation. In particular, the lexical-conceptual basis for UNITRAN, an implemented machine translation system, ...
Causal/Temporal Connectives: Syntax and Lexicon
(1989-09-01)
This report elucidates the linguistic representation of temporal relations among events. This involves examining sentences that contain two clauses connected by words like once, by the time, when, and before. Specifically, ...
An Object-Oriented Software Reuse Tool
(1989-04-01)
The Object-oriented Reuse Tool (ORT) supports the reuse of object-oriented software by maintaining a library of reusable classes and recording information about their reusability as well as information associated with their ...
Networks and the Best Approximation Property
(1989-10-01)
Networks can be considered as approximation schemes. Multilayer networks of the backpropagation type can approximate arbitrarily well continuous functions (Cybenko, 1989; Funahashi, 1989; Stinchcombe and White, 1989). We ...
