Protocol Modeling, Bifurcation/Bootstrapping, And Convince Me: Computer-Based Methods For Studying Beliefs And Their Revision
This paper traces a progression of four computer-based methods for studying and fostering both the structure and the on-line development of knowledge. Each empirical technique employs ECHO, a connectionist model…

The Use of Binocular Vision for Hazard Detection and Vehicle Control
We integrated two modules consisting of a new, domain-specific binocular stereo algorithm, and a lane marker detection algorithm, and show that the integration results in improved performance for each of…

Knowledge Representation in the Large
We describe the design and implementation of a storage subsystem that submerges a database management system (DBMS) within a knowledge representation system.

Learning In Interactive Environments: Prior Knowledge And New Experience
Educators often focus on the ideas that they want their audience to have. But research has shown that a learner’s prior knowledge often confounds an educator’s best efforts to deliver…

No Girls Allowed
Discusses girls' use of computers and examines why they are often discouraged and lose interest.

Ziplock Snakes
We propose a snake-based approach that lets a user specify only the distant endpoints of the curve he wishes to delineate without having to supply an almost complete polygonal approximation.

Indefeasible Semantics and Defeasible Pragmatics
I propose a fine structure of the preferential interpretation in pragmatics in terms of defeasible rule interactions. A logical implementation of the preferential rule interactions is proposed using prioritized circumscription,…

Distinguishing Knowledge Bases and Data Bases: Who’s on First and What’s on Second
This paper compares and contrasts relational data base management systems (RDBMSs) and frame knowledge representation systems (FRSs). We compare the capabilities that RDBMSs and FRSs provide to designers and users…
