Preparing Tomorrow’s Teachers to Work in Learning Communities
This paper proposes a collaborative approach to building knowledge that integrates theory and practice in diverse contexts. "Lesson study circles" (similar to learning circles and to ThinkQuest teams) are proposed…

Prosody-Based Automatic Segmentation of Speech into Sentences and Topics
Using decision tree and hidden Markov modeling techniques, we combine prosodic cues with word-based approaches, and evaluate performance on two speech corpora, Broadcast News and Switchboard. Results show that the…

An Ontology for Biological Function Based on Molecular Interactions
The article explores the notion of computing with function, and explains the importance of ontologies of function to bioinformatics.

A Framework for Describing Variations in State Early Intervention Systems
As part of the National Early Intervention Longitudinal Study, information about the early intervention service systems in the 20 participating states was gathered. This article organizes this information into dimensions…

A Survey of Research in Distributed, Continual Planning
In this article, we describe a new paradigm for planning in complex, dynamic environments, which we term distributed, continual planning (DCP). We argue that developing DCP systems will be necessary…

Coordinating Planning Activity and Information Flow in a Distributed Planning System
Distributed SIPE (DSIPE) is a distributed planning system that provides decision support to human planners in a collaborative planning environment.

Data-Driven Subclassification of Disfluent Repetitions Based on Prosodic Features
This study delves into the acoustic and prosodic information of repetitions, one of the most common disfluencies. A hierarchical clustering of prosodic features reveals three subsets of repetitions, each reflecting…

Phonetic Consequences of Speech Disfluency
Analyses of American English show that disfluency affects a variety of phonetic aspects of speech, including segment durations, intonation, voice quality, vowel quality, and coarticulation patterns. These effects provide clues…

Combining Words and Prosody for Information Extraction from Speech
In this work we demonstrate the use of em prosodic cues, alone and in combination with words, for segmentation and name finding. In experiments, we find that prosodic cues alone…

Characterizing the Performance of Multiple-Image Point-Correspondence Algorithms using Self-Consistency
A new approach to characterizing the performance of point- correspondence algorithms is presented.
