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 ...
SQUIRT: The Prototypical Mobile Robot for Autonomous Graduate Students
(1989-07-01)
This paper describes an exercise in building a complete robot aimed at being as small as possible but using off-the-shelf components exclusively. The result is an autonomous mobile robot slightly larger than one cubic ...
Twilight Zones and Cornerstones: A Gnat Robot Double Feature
(1989-07-01)
We want to build tiny gnat-sized robots, a millimeter or two in diameter. They will be cheap, disposable, totally self-contained autonomous agents able to do useful things in the world. This paper consists of two parts. ...
The Standard Map Machine
(1989-09-01)
We have designed the Standard Map Machine(SMM) as an answer to the intensive computational requirements involved in the study of chaotic behavior in nonlinear systems. The high-speed and high-precision performance of ...
Qualitative Depth and Shape from Stereo, in Agreement with Psychophysical Evidendence
(1987-12-01)
Obtaining exact depth from binocular disparities is hard if camera calibration is needed. We will show that qualitative depth information can be obtained from stereo disparities with almost no computations and with ...
UNITRAN: An Interlingual Machine Translation System
(1987-12-01)
This report describes the UNITRAN (UNIversal TRANslator) system, an implementation of a principle-based approach to natural language translation. The system is "interlingual", i.e., the model is based on universal ...
Software Structuring Principles for VLSI CAD
(1987-12-01)
A frustrating aspect of the frequent changes to large VLSI CAD systems is that so little of the old available programs can be reused. It takes too much time and effort to find the reusable pieces and recast them for ...
