Technology Integration and Demonstration
USC Information Sciences Institute
Sponsor: Ron Larsen, Defense Advanced Research Projects Agency, Information Technology Office
www.ISI.edu/geoworlds
Electronic Commerce: managing commerce in complex, custom services
Military/commercial command and control:
Component based technology needed to address recurrent problems
Improve visibility
of partners
Reduce isolation
between activities
Open up
rigid processes
Representations, collaboration environments, agent technology needed to express & act upon tradeoffs
Search/matchmaking aids, product/service taxonomies needed

Goals of GeoWorlds
Show current potential of technology for crucial applications (e.g., Disaster Relief)
Identify promising future directions
Core Ideas
What?
Regional Vision: marshal everything known about an area, displayed in space and time, to help understand a situation
How?
Rich geographic visualization
external vs. internal information
web documents, map information:
local plans and schedules
For Who?
"When and where were outbreaks of unrest reported in Chiapas?”
"What do we know about the region west of Baghdad?"
Command Post of the Future
Placing reports from the field in geospatial context
Transnational Threat Assessment
“What’s the implication of placing my base of operations here?”
Other applications
Sample: The Future
See what’s known
Focus on a sub-region
Extract, analyze, simulate, model
Disaster Relief Application and Components

Philosophy Behind the Schedule of Work
Short fuse
Many participants
High visibility/risk
Advance planning
Integration threads
Incremental Build Approach
Example: 3rd Fleet Disaster Relief Preparedness Planning Template
Types of
Tools for identifying and organizing information of interest:
Collaborative Development of Thematic Navigators
Multiple tools:
Rapid focus on information about incident region
Identify affected areas
Select information desired
Inspect documents, organized by function
Pull up documents about the area
Pull up information as needed
Develop additional information on-the-fly
Status (as of 26 Oct 98)
Technical team in place, kick-off meeting held 4-5 June, 1998
ISI / SPAWAR collaborating on scenario in consultation with PACOM
Chem/bio incident impacting San Diego
First three integration meetings held
PACOM signed up as testbed user after receiving demo of release 3
Also demonstrated at Internet2, San Francisco, Sept. 28-30
Shown to San Diego Disaster Response First Responders Council, Oct 5
Release 4 now being shown in demos
Information Management P/I Meeting & PACOM, Honolulu, Oct. 26-30
Supercomputing / Next Generation Internet, Orlando, Nov 9-12
Scheduled for demonstration in NATO Exercise, April 99
What’s in GeoWorlds - the Demo?
Now
Component clustering technologies
Concept of a service registry / service selection
(Slow) analysis of region-document relations
(Unstructured) annotation - asynchronous collaboration
What’s in GeoWorlds - the Future?
A Partial List of Challenges
Geographic Visualization
Analysis speed
Intelligent integration of services
Summarization/focusing: what really matters?
DASHER: Task-Oriented Information Repositories
Organizational services
(Who can provide this part, design this aspect, perform this assessment, process this data, ...?)
Computation services
(Can I use this simulation, get this data transformed, automate this interaction, …?)
INFORMATION
books
pictures
maps
videos
Traditional
buyers, engineers...
Information discovery, …
Info includes both digital library stuff, EC info, product spec., ...
How to build this information repository -> topic of this talk
Collaboration between info/service seekers and providers
Subtle issue: Understanding frame of reference (terminology, ontology, …)
Don’t know who to talk to, how to talk to them until you understand the category mappings
Collaboration between information seekers
allow seekers to share information from remote locations in real time over the Internet.
Habanero-izing DASHER
Building Connections
Collaboration Lifecycle
DASHER Tools
Gives users means of identifying topics of interest to them
Help them structure the space of data sources accordingly
Focus on helping user develop and assess alternatives
Inter-Service Negotiation Tools
Help define specific nature of customized service/product
Toward this goal DASHER is building two suites of tools
Information Space Analysis Tools - the focus of this talk
Inter-Service Negotiation Tools - new, we’re excited about, hope to present in next year’s WETICE meeting
Focus of DASHER is not retrieve THE document that will satisfy the informational needs of the user, but to make sense of sets of data sources.
Significant Features of Current
Example: scouting services/info/expertise needed for a tiger
team to rapidly build a product with embedded GPS capabilities
Problem: need to understand
finding a particular document
(try to find an unfamiliar service in the Yellow Pages)
Component tasks that other tools don’t support:
Scoping the relevant pool of materials to look at
Understanding how others have organized candidate materials
Relating their categorizations to the way you want to think about it
Keeping track of several questions at once

Characterize document sets using word-based rules
Use rule-induction tool (Ripper) to generate the rules
Use Document sets from Yahoo as training examples
Rules: more understandable than vector models
