Terregov eGovernment interoperability on a
semantically driven world

• Interop-ESA/eGov Interop conference
• Geneva, February 2005
• Santos Vicente, María Pérez, Xavier García, Ana

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.

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.

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.
