Online Query Relaxation via Bayesian Causal Structures Discovery
We introduce a novel algorithm, TOQR, for relaxing failed queries over databases, that is, over-constrained DNF queries that return an empty result.
-
Querying and Computing with BioCyc Databases
We describe multiple methods for accessing and querying the complex and integrated cellular data in the BioCyc family of databases.
-
Morphology induction from term clusters
We address the problem of learning a morphological automaton directly from a monolingual text corpus without recourse to additional resources.
-
Modeling Prosodic Feature Sequences for Speaker Recognition
We describe a novel approach to modeling idiosyncratic prosodic behavior for automatic speaker recognition.
-
Activity Recognition and Abnormality Detection with the Switching Hidden Semi-Markov model
We introduce the Switching Hidden Semi-Markov Model (S-HSMM), a two-layered extension of the hidden semi-Markov model (HSMM) for the modeling task.

Angler: Collaboratively Expanding your Cognitive Horizon
The tool helps the group through the process of forming consensus, while preserving and quantifying differing ways of thinking. Angler provides a Web-based collaborative environment that allows users distributed by…

Human-aided multi-sensor fusion
This paper discusses some fundamental requirements for a human-aided multi-sensor fusion system, and proposes an approach that implements such a system. This approach involves integration of the probabilistic argumentation system…
