Misconceptions Reconceived: A Constructivist Analysis Of Knowledge In Transition
This article uses a critical evaluation of research on student misconceptions in science and mathematics to articulate a constructivist view of learning in which student conceptions play productive roles in the acquisition of expertise.

The Design and Assessment of A Hypermedia Course on Semiconductor Manufacturing
Learning effects were assessed. Results suggest that subjects who browsed via hypermedia links tended to more often bridge topic areas rather than explore them in depth, but there were little or no learning differences by knowledge or navigation group, and neither prior interest nor nodes viewed (by number, topic area, or media type) were correlated…

Fastus: A System For Extracting Information From Natural-Language Text
FASTUS is a system for extracting information from free text in English, and potentially other languages as well, for entry into a database, and potentially for other applications. It works essentially as a cascaded, non-deterministic finite state automaton.

Connectionist Gender Adaptation in a Hybrid Neural Network / Hidden Markov Model Speech Recognition System
An approach to modeling long-term consistencies in peech signal within the framework of a hybrid Hidden Markov Model (HMM) / Multilayer Perceptron (MLP peaker-independent continuous-speech recognition system is presented.

Characterizing diagnoses and systems
In this paper we analyze the concept of diagnosis in depth exploiting the notions of implicate/implicant and prime implicate/implicant.

Integrating Multiple Knowledge Sources for Detection and Correction of Repairs in Human-computer Dialog
We present here criteria and techniques for automatically detecting the presence of a repair, its location, and making the appropriate correction. The criteria involve integration of knowledge from several sources: pattern matching, syntactic and semantic analysis, and acoustics.

The Representation Space Paradigm Of Concurrent Evolving Object Descriptions
This paradigm is designed to be used by the perception system of an autonomous robot that needs to describe many types of objects, initially detects objects at a distance and gradually acquires higher resolution data, and continuously collects sensory input.
