At the Boundary of Workflow and AI
This paper describes how techniques from the AI community, specifically reactive control, planning, and scheduling, could be leveraged to develop powerful, next-generation adaptive workflow engines that provide many of the…

Task-based Information Management
We are constructing a system, called the Task-based Information Distribution Environment (TIDE), that delivers information to participants in a dynamic collaboration by evaluating the relevance of incoming and newly generated…

Construct Validation Of Mathematics Achievement: Evidence From Interview Procedures
This study investigated the validity of measures derived from a large-scale multiple-choice achievement test in mathematics, using evidence from introspective think-aloud protocols of students as they attempted test items.

Reconfigurable Elements for a Video Pipeline Processor
This paper describes a family of reconfigurable processing elements (RPEs) used to support video processing for the Sarnoff Vision Front End 200 (VFE-200) vision system.

3–D Stereo Reconstruction of Human Faces driven by Differential Constraints
We propose a way to incorporate a priori information in a reconstruction process from a sequence of calibrated face images.

The Probability Inquiry Environment: A Collaborative, Inquiry-Based Simulation Environment
We report on the Probability Inquiry Environment (PIE), which facilitates the development of probabilistic reasoning by making available collaborative inquiry activities and student-controlled simulations.

Prolegomena to a Theory of Disability, Inability and Handicap
In this paper we extend a theory of action, IPT to try to elucidate these concepts. This attempt at elucidation is itself at most a prolegomena to a study that…

Combining Words and Speech Prosody for Automatic Topic Segmentation
We present a probabilistic model that uses both prosodic and lexical cues for the automatic segmentation of speech into topic units. The approach combines hidden Markov models, statistical language models,…

Information extraction using HMMs and shrinkage
This paper advocates for the use of HMMs for information extraction.
