  1. Database Middleware for Distributed Ontologies in State and Federal Family & Social Services A.K. Elmagarmid A. Bouguettaya Purdue UniversityVirginia Tech URL www.nvc.cs.vt.edu/~dgov Objective To develop an infrastructure that would: • Help the citizens of Indiana get timely information from government agencies. • Enable disadvantaged citizens (e.g., physically challenged) have most of their needs satisfied in one single meeting.

  2. About the Project • Supported by • National Science Foundation (NSF) • HP Equipment Grant • Coordinated proposal from • Purdue University • Virginia Tech • Project partners • Family and Social Services Administration • Department of Health and Human Services

  3. People • Project Investigators • Professor Ahmed K. Elmagarmid, Purdue University • Professor Athman Bouguettaya, Virginia Tech • Project Partners • Jerry Cameron, Director, Office of Architecture and Standards, FSSA • Graduate Students • Brahim Medjahed, Virginia Tech • Mourad Ouzzani, Virginia Tech • Emine Yurtserver, Purdue University

  4. Collaboration withGovernment Agencies • Indiana Family and Social Services Administration (FSSA) Mission: Helping low-income families people with mental illness, addiction, etc. • US Department of Health and Human Services (HHS) Mission: protecting the health of all Americans and providing essential human services

  5. Contribution • 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

  6. Overview of FSSA-relatedInformation Systems Indiana Client Eligibility System Welfare Referral Integrated Database To HHS To HHS Medicaid System Indiana Support Enforcement Tracking Systems Child Care Information System Indiana Child Welfare Information System Department of Workforce Development Federal Parent Locator Service (HHS) National Directory of New Hires

  7. Motivating Scenario (1) -Collecting Benefits Division of Family and Children (DFC) Single Mother (1) Visit the DFC Child care voucher agency (4) (3) (2) Visit the child care voucher agency Register in CS3 Register for TANF (5) Find a certified caretaker Certified child caretaker Department of Workforce Development

  8. Motivating Scenario (2) -Helping Disabled People -Training to get a job -Help to be self-dependent -Refurbishing home to be disabled friendly, etc. Services within and outside The VR office Visit the VR Office Disabled Person Vocational Rehabilitation Office (VR)

  9. Approach –Distributed Ontologies • Definition • Meaningful organization of the FSSA-related information space • Dynamically lump databases together based on common areas of interest (e.g., Low Income ontology) • Why? • 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

  10. Ontological Support Law Enforcement Low Income Transportation Mental Retardation Disability State bureau of investigation Job training Medical services Police department Child care Vocational rehabilitation State patrol Food stamps Residential support Medicaid system ISETS WIC Government Agencies Department of justice Credit bureau IRS Medicaid Department of employment Finance

  11. Helping Citizens and Case Mangers Case Manager Interface User Interface

  12. Related Research Issues • Query Infrastructure • Describe, advertise and query information sources and meta-information repositories • Educate citizens and case managers about the information space • Agent Middleware • 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)

  13. Enabling Technologies • Java • RMI (Remote Method Invocation) • JDBC (Java DataBase Connectivity) • Distributed computing platforms • CORBA - Orbix, OrbixWeb, VisiBroker for Java • EJB (Enterprise JavaBeans) • ActiveX/DCOM • Databases - Oracle, Informix, Sybase, DB2, ObjectStore, SQL Server • Agents - IBM Aglets, Voyager • XML - Java API for XML Parsing, Oracle XML parser for Java

  14. Software and Hardware • NCR Teradata server (80 Intel processors, 20 gigabytes of main memory, 400 disk drives) • 30 Sun workstations Ultra-10 • 40 Intel Workstations and PCs • Software systems: Unix, Windows NT

  15. Collaboration withOther Organizations • Several industrial partners including Sun, HP, NCR, and Telcordia • Indiana-based social service organizations
