Title: Implementing Semantic Web in Government


1
Implementing Semantic Web in Government
  • An SLA 2006 conference program sponsored by the
  • Information Technology Division
  • and the
  • Government Information Division

2
Program Schedule
  • Overview of implementing the Semantic Web using
    the Data Reference Model and the Categorization
    Working Group of the Interagency Committee on
    Government Information (ICGI)
  • Richard Huffine, U.S. General Services
    Administration/FirstGov
  • Semantic Web in use in government - Case studies
    using Federal Enterprise Architecture NASA
    Digital Shuttle Project, FAA, and GSA
  • Dean Allemang, Top Quadrant Consulting
  • Semantic interoperability and library skills
    (taxonomy, metadata management, etc.)
  • Marjorie Hlava, Access Innovations

  • "The Semantic Web is an extension of the current
    web in which information is given well-defined
    meaning, better enabling computers and people to
    work in cooperation.

  • The Semantic Web is a project to make the content
    of the World Wide Web understandable by machines.
    It extends the ability of the World Wide Web
    through the use of standards, markup languages
    and related processing tools.

What Is the Semantic Web?
  • The Semantic Web is an extension of the current
    Web that will allow you to find, share, and
    combine information more easily. It relies on
    machine-readable information and metadata
    expressed in RDF.
  • www.noisebetweenstations.com/personal/essays/metad
    ata_glossary/metadata_glossary.html
  • Resource Description Framework (RDF) is a general
    framework for how to describe any Internet
    resource such as a Web site and its content.

Semantic Web in Government
  • Government Agencies are struggling with issues of
    repetition in data collection, barriers to
    sharing information, and increasing expectations
    to do more with less
  • The U.S. E-Gov Agenda (and the Partnership for
    Reinventing Government before it) sets
    expectations that Agencies will work together to
    solve common business problems
  • After September 11, 2001, the intelligence
    community has stepped up their efforts to make
    their information interoperable with other
    intelligence and law enforcement entities

7
Categorization Working Group
  • Convened in 2003 to recommend approaches for
    implementing the E-Gov Act
  • Comprised of U.S. Federal staff, mostly
    librarians
  • Focused on defining a clear scope and approach to
    the categorization of information in order to
    improve access to government information that is
    born digital
  • Intended to build on the past (bibliographic
    records) and incorporate new approached for the
    future
  • Recommendations were rolled into the
    implementation of the Data Reference Model of the
    Federal Enterprise Architecture
  • See a video series on the topic at

Federal Enterprise Architecture
  • A set of common frameworks for describing
    information systems and their interdependencies
  • Requires Agencies and Departments to document
    their current and target architectures and then
    justify Information Technology expenditures in
    support of achieving that target architecture
  • Encourages organizations to share components and
    reduce the duplication of effort (through
    coordinated E-Gov Initiatives like Grants, Travel
    and Financial Management

Data Reference Model
  • Version 2.0 released in November, 2005
  • There are two basic types of metadata recommended
    in the Data Description section of the DRM
    abstract model
  • Logical data models to describe Structured Data
    Resources, and
  • Digital Data Resource metadata (such as Dublin
    Core elements) to describe Semi-Structured and
    Unstructured Data Resources.
  • Recommendation stopped short of recommending
    specific standards but acknowledges that various
    standards can be mapped to one another to create
    a minimal amount of interoperability
  • http//www.whitehouse.gov/omb/egov/a-5-drm.html

Data Reference Model (continued)
  • Agency implementation of the Data Reference Model
    is slow
  • Much of the utility of the FEA to date has been
    driven by IT Investment decision-making, not by
    the need to share information with other Agencies
  • The primary exception, intelligence, has made
    real progress although much of it is classified
  • The Data Reference Model supports semantic
    interoperability but it does not mandate its
    implementation.
  • Agencies are still struggling with both the
    business and cultural needs for sharing
    information

In the News
  • New Scientist has discovered that Pentagon's
    National Security Agency, which specialises in
    eavesdropping and code-breaking, is funding
    research into the mass harvesting of the
    information that people post about themselves on
    social networks. And it could harness advances in
    internet technology - specifically the
    forthcoming "semantic web" championed by the web
    standards organisation W3C - to combine data from
    social networking websites with details such as
    banking, retail and property records, allowing
    the NSA to build extensive, all-embracing
    personal profiles of individuals.
