  1. Let the Citizen Speak:A demand-driven e-government portal using Semantic Web Technology Erhat Ilgar1, John Oldenhuizing2 Peter Mika3 Ordina1 Zenc2 Vrije Universiteit, Amsterdam3 Semantic Web and e-Government AAAI Spring Symposium 2006

  2. overheid.nl • Central point for electronic government information • No e-services • Maintained by the Dutch government agency ICTU on behalf of the Ministry of the Interior and Kingdom Relations (MinBZK). • Catalogue and search facility for 1300+ governmental website in the Netherlands

  3. overheid.nl

  4. Problem A tale of many trees… Organizations Products Laws Residence permit Immigration Act article 14 IND

  5. Solution • Lift XML trees into RDF/OWL. • Map ontologies. • Keep doing it.

  6. A smarter way 1.7 million records 1.1 million searches 415 000 (29%) • Let the citizens do the work! 4000 words!

  7. Method • Emergent, bottom-up semantics: • Relate search terms to concepts • Many-to-many • Part manual, part automated • Find relationships (mappings) between concepts based on shared terms Residence permit Immigration Act article 14 IND “verblijfsvergunning”

  8. Advantages • Live, dynamic ontologies Mappings are emergent, not fixed. No more “mind-reading and fortune-telling”. • Relationships follow changing conceptualizations • e.g. temporal search • We know what people will be looking for on September 19, 2006 (and how they relate that day!) • e.g. personal search • What did people like you search for • Citizen’s view • Ontology by vox populi vs. ontology by bureaucracy • There is no such thing as a wrong question

  9. Future work • Use method for (semi) automatically maintaining ontologies • Suggest new terms, terms for removal • More direct impact on navigation • Improvements in supply-side • Use this technique for meta-data embedded in Web pages • Complement controlled vocabularies

  10. Related work • In the Semantic Web domain • Folksonomies, tagging systems, bottom-up approaches to semantics • In the eGov domain • “The citizen’s language of the City” (Den Bosch) On a sunny day , the 28th of June in 2003, about 250 citizens, armed with camera’s and coached by 40 guides were sent along ten promenades through the old city of Den Bosch. Their mission: record your impression of that assigned neighbourhood, take three pictures that cover this impression in five single term keywords and go on to the next one on the route. Together they took 5000 pictures and wrote down 7000 keywords.
