Dialogue Act Modeling for Automatic Tagging and Recognition of Conversational Speech
We describe a statistical approach for modeling dialogue acts in conversational speech, i.e., speech-act-like units such as Statement, Question, Backchannel, Agreement, Disagreement, and Apology. Our model detects and predicts dialogue…

Automatic Generation of Compact Programs and Virtual Machines for Scheme
We use a combination of techniques to automatically generate new instructions and new compact encodings for virtual instructions.

Do Technology Investments Pay Off? The Evidence Is In!
In a 5-year evaluation of the $6.6 million Challenge 2000 Multimedia Project, technology-using students surpassed nonparticipating peers in developing critical 21st-century job skills.

Effects of Speech Recognition-based Pronunciation Feedback on Second-Language Pronunciation Ability
This study's goal was to determine whether receiving a particular type of feedback on nativeness of second-language accent positively influenced pronunciation over time.

The SRI EduSpeak(TM) System: Recognition and Pronunciation Scoring for Language Learning
The EduSpeak(TM) system is a software development toolkit that enables developers of interactive language education software to use state-of-the-art speech recognition and pronunciation scoring technology.

Structured Argumentation for Analysis
We are developing a new methodology that retains the ease-of-use, familiarity, and (some of) the free-form nature of informal methods, while benefiting from the rigor, structure, and potential for automation…

Reusing Prior Knowledge: Problems and Solutions
In this paper, we focus on the process of reuse and report a case study on constructing a KB by reusing existing knowledge. The reuse process involved the following steps:…

Word-Level Rate of Speech Modeling Using Rate-Specific Phones and Pronunciations
We propose to use rate-specific phone models and pronunciations for ROS modeling at the word level. Words are given three types of pronunciations -- fast, slow, and medium -- consisting…

Interactions of DnaA proteins from distantly related bacteria with the replication origin of the broad host range plasmid RK2
In this study we compared the interactions of oriV with five different DnaA proteins.

Multiple-Target Tracking and Data Fusion via Probabilistic Mapping
A new approach is taken to address the various aspects of the multi-sensor, multi-target tracking (MTT) problem in dense and noisy environments. Instead of fixing the trackers on the potential…

Detecting Changes in 3-d Shape using Self-Consistency
A novel image-matching measure based on Minimum Description Length (MDL) theory allows us to estimate the accuracy of individual elements of the 3- D model. Experiments to demonstrate the utility…

Measuring the Self-Consistency of Stereo Algorithms
A new approach to characterizing the performance of point-correspondence algorithms is presented. Instead of relying on any "ground truth", it uses the self-consistency of the outputs of an algorithm independently…
