Title: Terregov: eGovernment interoperability on a semantically driven world

Terregov eGovernment interoperability on a
semantically driven world
  • Interop-ESA/eGov Interop conference
  • Geneva, February 2005
  • Santos Vicente, María Pérez, Xavier García, Ana
    Gimeno, María Pérez terregov_at_gfi-info.com

Overview
  • Government Administrations need
  • procedures integration,
  • distributed responsibilities,
  • agencies interaction.
  • Semantic Interoperability Technologies solutions
  • standardisation of business concepts,
  • automatic search on concepts,
  • automatic service discovery.
  • Developments
  • semantically enabled web services,
  • practical experiences research and enterprise
    world.

eGovernment
  • Interconnections in remote public services.
  • Access to procedures in a transparent manner.
  • Need of more distributed and inter-linked
    processes.
  • Difficult to establish standards and
    heterogeneous procedures.
  • Common knowledge is a key feature.
  • Interoperability
  • sharing information and exchanging data.
  • organisational issues.
  • security issues authentication and certification
    procedures.

4
eGovernment Solutions
  • Web Services as a way of access and discover
    interoperable information in agencies.
  • Web Services benefits
  • Interoperability expose functionality to other
    applications.
  • any platform, any programming language.
  • e-business process efficiency.
  • Implementation of automated systems, service
    discovery and systems interaction.
  • Lack of semantic definitions in traditional web
    services
  • Addition of semantics allow a better integration
    between agencies and dynamic service discovery.

5
Semantic Technologies
  • Innovative implementation for eGovernment
    solutions.
  • Semantic web benefits
  • Efficient exchange and interoperation among
    agencies.
  • Standardise information as concepts.
  • Enable automatic service discovery.

6
Semantic web knowledge representation
  • Ontology describe and represent
    interrelationships of the information in a
    domain.
  • RDF Resource Definition Framework.
  • OWL Web Ontology Language
  • XML markup language to describe concepts,
    attributes and relationships among them.
  • OWL-S Web Ontology Language for Web Services
  • Standard to describe web services specifications
    unambiguously.
  • Facilitates automation of web services discovery,
    interoperation, invocation and monitoring.
  • Definition of the profile, the process model and
    the grounding of the service.

Semantic Applications
  • eGovernment
  • SWAD Semantic Web Advances Development in
    Europe.
  • Ontogov platform for eGovernment services.
  • Emayor municipal eGovernment applications.
  • Terregov eGovernment on Territorial Government
    Services.
  • Commercial Products
  • Kalido data warehousing software.
  • Semagix enterprise content management

9
Terregov
  • European Union funded project to enable local
    governments to deliver online services in a
    transparent manner within european countries.
  • Semantic enrichment of web services and
    information using ontologies
  • language-independent mechanism,
  • structured knowledge,
  • automatic discovery of a request,
  • web services standards,
  • addition of semantic descriptions.
  • European pilots administrations in the social
    care context.

Conclusions
  • eGovernment interoperability achieved by
    standardising public administrations.
  • Security and legislative constraints.
  • Semantic technologies
  • add efficiency in the exchange of information and
    services among agencies.
  • interoperability among systems in a transparent
    manner.
  • dynamic web service discovery.
  • Semantic solutions in eGovernment evolve in
    parallel with semantic technologies, which are in
    an ongoing research stage.
