Prosodic Knowledge Sources for Automatic Speech Recognition
We investigate three models, each exploiting a different level of prosodic information, in rescoring N-best hypotheses according to how well recognized words correspond to prosodic features of the utterance.

A Prosody-based Approach to End-of-Utterance Detection That Does Not Require Speech Recognition
In this paper we demonstrate that the improvements due to the prosodic knowledge can be realized largely without alignment information, i.e., without requiring a speech recognizer. A prosodic end-of-utterance detector…

The Robustness of an Almost-Parsing Language Model Given Errorful Training Data
An almost-parsing language model has been developed that provides a framework for tightly integrating multiple knowledge sources. Lexical features and syntactic constraints are integrated into a uniform linguistic structure (called…

Training a Prosody-Based Dialog Act Tagger from Unlabeled Data
Here we investigate the use of unlabeled data for training HMM-based dialog act taggers. Three techniques are shown to be effective for bootstrapping a tagger from very small amounts of…

Fast Symbolic Evaluation of C/C++ Preprocessing Using Conditional Values
We present a new approach for symbolic evaluation that can efficiently compute these conditions by binding variables to conditional values and avoiding the path feasibility analysis of traditional symbolic evaluation.

Interactive Execution Monitoring of Agent Teams
We describe a monitoring framework for integrating many domain-specific and task-specific monitoring techniques and then using the concept of value of an alert to avoid operator overload.

Design Patterns For Assessing Science Inquiry (Padi Technical Report 1)
This paper reports progress on one facet of PADI: design patterns for assessing science inquiry. Design patterns bridge knowledge about aspects of science inquiry that one would want to assess…
