Access-eGov projectFull title: Access to e-Government Services Employing

Semantic Technologies

www.accessegov.org• Starting date: January 1st, 2006• Duration: 36 months• EC Funding: 1.983.000 €• Total Budget: 2.279.243 €

Main goal: to develop and validate a platform for composition of

government services into complex process definitions (covering

life events/business episodes) enabling semantic interoperability of

particular e-Government services.

Objectives & FunctionalityAccess-eGov system: a framework / platform for eGov

services, based on Semantic Web technologies.

Provided services:• Meta-service will identify proper eGov services relevant to the

given life event or business episode (according to the semantically expressed user‘s needs & requirements),

• Scenarios consisting of elementary eGov services (of „hybrid“ nature, i.e. a combination of traditional and electronic eGov services),

• Virtual Personal Assistant - a tool that will guide users in the space of available services.

In Slovakia: land-use planning and processing a request for a building permit.

In Poland: establishing an enterprise taking into account the process of company registration.

In Germany: an upgrade and field test based on the existing good practice, the so-called “Zustaendigkeitsfinder” ("Responsibility Finder"), by introducing a semantic layer (securing semantic interoperability between national and local

governments).

In Egypt (German University of Cairo): searching for eGov services provided by an EU country. Use case: applying for a work permit in an EU country.

Architecture contextSecurity requirements: Privacy (secure personal info), Communication

security (data encrytion), Access Control, Trust between nodes.

General functional reqs: Reliability (Maturity, Recoverability, Fault tolerance - SoA: components not tightly coupled), Efficiency (caching, effective storage layer).

User reqs: eSignature for transactional operations (e. g. invoking services, filling in electronic forms), XML based interface available (including exchange of user information if user permits), Tracing business processes, Retrieval of services / life events, Scenario construction, Personalisation, Multilinguality, etc.

Data reqs: Changeability (esp. on Ontology level), Reusability (Knowledge storage is decoupled from other components), Suitability (rich set of knowledge concepts for semantic descriptions).

Conceptual Architecture (1)Security view• Single-Sign-On (SSO) functionality• Solution allows public agencies to keep their own preferred technology for

user authenticationFunctional view• Annotation of services, effective data storage• Retrieval of services according to certain citizen requests • Stringing annotated services together to form new “meta services” -

scenariosData view• Ontologies - semantic description of real-world concepts• Ontologies used:

– Life events ontology– Service profiles ontology– Access-eGov Domain ontology

Future work• Specification of components: (almost finished)

• Annotation services & Ontologies: design and development of data repositories and functional components for semantic description and annotation of eGov services

• Implementation of the core Access-eGov system

• Pilot applications, development and customization of the system for particular pilot application

• Testing, evaluation
