Collaborative Modeling: Hiding UML And Promoting Data Examples In NEMo
We describe a Web-based tool for modeling that creates and manipulates a simple data model without representing it in UML, while promoting collaboration and the use of examples to compare…

A Bayesian method for identifying missing enzymes in predicted metabolic pathway databases
We have developed a method that efficiently combines homology and pathway-based evidence to identify candidates for filling pathway holes in Pathway/Genome databases.
-
Towards a Quantitative Platform Independent Analysis of Knowledge Systems
The Halo Pilot collaboratively developed a taxonomy of failures with the goal of creating a common framework of metrics against which we could measure inter- and intra- system failure characteristics…

A Multimodal Learning Interface for Sketch, Speak and Point Creation of a Schedule Chart
We present a video demonstration of an agent-based test bed application for ongoing research into multi-user, multimodal, computer-assisted meetings.
-
Toward a Theory of Qualitative Reasoning about Plans
We define a qualitative framework for reasoning about plan structure, defining a set of plan relations that characterize key interactions among plan components and a calculus for reasoning qualitatively about…
