Aquaint: From Question-Answering to Information Seeking Dialogs
From question-answering to information-seeking dialogs.
 

Coordination of Distributed Activities (CODA)
The CODA system provides targeted information dissemination among distributed planners as a way of improving team coordination. In CODA, an individual planner declares interest in different types of plan changes that could impact his local plan development. As a team of distributed users develop plans with a plan authoring tool, their activities are monitored; changes that match declared interests are forwarded automatically to the person who declared interest in them.
 

Deductive Composition of Multiple Data Sources
A framework is being developed for composing answers to queries, using automated deduction and multi-agent information brokering, based on multiple information sources. The technology is being applied to answering geographical queries for ecological modeling, based on NASA EOSDIS satellite imagery, map data, and gazetteer information.
 

Inferring Intent of Attackers
CAPRE uses plan recognition techniques to automatically determining the intent behind a cluster of security alerts. This allows us to prioritize and explain alert clusters to users.
 

Plan Authoring System based on Sketches, Advice, and Templates (PASSAT)
PASSAT is a user-centric plan-authoring system grounded in the concepts of plan sketches, advice, and templates. PASSAT enables users to quickly develop plans that draw upon past experience encoded in templates, but that are customized to their individual preferences of a given user. The PASSAT core consists of an interactive plan authoring capability; tools for task management, constraint reasoning, plan sketching and causal reasoning provide provide complementary automated capabilities.
 

The JFACC Planner/Scheduler
The main accomplishment on the project was the development of an integrated planning and scheduling capability that supports generation of tightly linked air operations plans and schedules, as well as their adaptation in response to changing tasks and resource availability. This effort built on existing planning (CPEF, from SRI) and scheduling (ACS, from CMU) technologies that provide core generation and repair techniques. (Joint work with Dr. Stephen F. Smith)
