Sampling Stable Properties of Massive Track Datasets
In this paper, we explore ways in which stable properties of sensor observations can be extracted and visualized using a statistical sampling of features from a very large track dataset, using very little ground truth or outside knowledge.

Modeling the Impact of Formal and Informal Supports for Young Children with Disabilities and Their Families
Findings reinforce the role of high-quality services in maximizing perceived impact. They also highlight the important role of informal support in promoting optimism and confidence in parenting. Poverty status, minority status, and poor health of the child are salient factors in predicting lower perceived quality of and benefit from services.

Capturing and Answering Questions Posed to a Knowledge-Based System
As part of the ongoing project, Project Halo, our goal is to build a system capable of answering questions posed by novice users to a formal knowledge base. In our current context, the knowledge base covers selected topics in physics, chemistry, and biology, and our question set consists of AP (advanced high-school) level examination questions.

Enabling Experts to Build Knowledge Bases from Science Textbooks
As a near-term goal, we are focusing on enabling subject matter experts (SMEs) to construct declarative knowledge bases (KBs) from 50 pages of a science textbook in the domains of Physics,Chemistry, and Biology in a way that the system can answer questions similar to those in an Advanced Placement(AP) exam in the respective discipline.

Comparison of US, EPO, and PCT Patent Citations for Citation Analysis
This paper summarizes the results of a statistical comparison of citations on patent documents from the U.S. Patent & Trademark Office (USPTO), the EPO, and the PCT to determine whether more information could be extracted from EPO and/or PCT citations than from using U.S. citations alone.

Extending Boosting for Large Scale Spoken Language Understanding
We propose three methods for extending the Boosting family of classifiers motivated by the real-life problems we have encountered. Our results indicate that it is possible to obtain the same classification performance by using 30% less labeled data when the unlabeled data is utilized through semisupervised learning.

Radio and Meteor Science Outcomes from Comparisons of Meteor Radar Observations at Amisr Poker Flat, Sondrestrom, and Arecibo
We address these meteor “head-echo” observations issues via the first ever use and analysis of meteor observations from the Poker Flat AMISR (PFISR: 449.3 MHz), Sondrestrom (SRF: 1,290 MHz), and Arecibo (AO: 430 MHz) radars.

Capturing a Taxonomy of Failures During Automatic Interpretation of Questions Posed in Natural Language
In this paper, we present a study – conducted in the context of the Halo Project – cataloging the types of failures that occur when capturing knowledge from natural language.
