Modeling Word Durations
We describe a new method of modeling duration at word level. These duration models are easily trained from the acoustic training data and can be used to rescore N-best lists…

Can Prosody Aid the Automatic Processing of Multi-Party Meetings? Evidence from Predicting Punctuation, Disfluencies,and Overlapping Speech
We investigate whether probabilistic modeling of prosody can aid various automatic labeling tasks essential for processing of multi-party meetings.

The GeoWeb — A New Paradigm for Finding Data on the Web
We propose to build and maintain this open standards-based infrastructure on a new top-level domain called .geo that will enable anybody to publish and search for all metadata referring to…

A Framework for Robust 3-D Change Detection
We present an application of our framework for 3-D object-centered change detection to combined satellite and aerial imagery.

Observations on Overlap: Findings and Implications for Automatic Processing of Multi-Party Conversation
We examine the distribution of overlapping speech in different corpora of natural multi-party conversations, including two types of meetings, and two corpora of telephone conversations.

Improved Maximum Mutual Information Estimation Training of Continuous Density HMMs
We derive a new set of equations for MMIE based on a quasi-Newton algorithm, without relying on EBW. We find that by adopting a generalized form of the MMIE criterion,…

Detecting Independently Moving Objects and Their Interactions in Georeferenced Airborne Video
In this paper, we describe a novel technique for detecting independent movement by analyzing georeferenced object motion relative to the trajectory of the camera. The method is demonstrated on over…
