government agencies.
 Enable disadvantaged citizens (e.g., physically challenged)
have most of their needs satisfied in one single meeting.


Improve citizen-government interactions
Bring government to citizens
Assist the citizens of Indiana for their special needs
Help the needy citizens collect the benefits they are
entitled to
Make government-related information available to citizens
and case managers
Provide a “one-stop” government-related services system

Approach –
Distributed Ontologies

Definition



Why?




Meaningful organization of the FSSA-related information space
Dynamically lump databases together based on common areas
of interest (e.g., Low Income ontology)
Filter interactions (citizens and case managers)
Accelerate information searches of FSSA-related information
systems
Allow the sharing of data among government agencies in a
tractable manner
How?


Codatabases: distributed meta-information repositories
Inter-ontology relationships: dynamically established based on
needs of citizens and case managers

Agent Middleware



Describe, advertise and query information sources and metainformation repositories
Educate citizens and case managers about the information space
Provide help to locate and use the requested information
Collect information about the history of users’ queries and monitors
the overall system
Dynamic Inter-ontology Relationships


Automatic notification in the event of noteworthy changes in the
pattern of users’ queries
Parameters that help determine the strength of relationships (e.g.,
number of traversals of a relationship path)
