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@gfi-info.com

overview
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
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.
egovernment solutions
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.

semantic technologies
Semantic Technologies
  • Innovative implementation for eGovernment solutions.
  • Semantic web benefits:
    • Efficient exchange and interoperation among agencies.
    • Standardise information as concepts.
    • Enable automatic service discovery.
semantic web knowledge representation
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
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
terregov
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
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.
