En verder nog meer algemene mapping’s:

•   Images. Links pointing at Wikimedia Commons images depicting a resource are extracted and represented
    by using the foaf:depiction property.

•   Redirects. In order to identify synonymous terms, Wikipedia articles can redirect to other articles. We
    extract these redirects and use them to resolve references between DBpedia resources.

•   External links. Articles contain references to external Web resources which we represent by using the
    DBpedia property dbpedia:reference.

•   Pagelinks. We extract all links between Wikipedia articles and represent them by using the
    dbpedia:wikilink property.

•   Homepages. This extractor obtains links to the homepages of entities such as companies and organisations
    by looking for the terms homepage or website within article links
•   Categories. Wikipedia articles are arranged in categories, which we represent by using the SKOS
    vocabulary4.

•   Geo-coordinates. The geo-extractor expresses coordinates by using the Basic Geo (WGS84 lat/long)
    Vocabulary5 and the GeoRSS Simple encoding of the W3C Geospatial Vocabulary6.

•   Metainformation. A new extractor which introduces organisational properties like direct edit links and oai
    identifiers for edit and delete operations.

Voorstel

1. nl.dbpedia.org en Extraction Framework inrichten
    door DBpedia team Leipzig ism Bibliotheek.nl

2. configuren/aanpassen software voor betere (taalgevoelige) harvesting
    door Bibliotheek.nl / DBpedia team / programmeurs ism UvA? Univ Gent???

3. invullen mappingsschema’s en uitbreiden ontologie en properties
     door IT/IP’ers via community ism Bibliotheek.nl / Bibnet (?)

4. beter invullen van de Infobox op de wikipedia pagina
    door community met ondersteuning van bibliotheekorganisaties en WikiMedia
discussie
• Goed idee?

• Gaat het werken via de community? Hoe moeten we dit opstarten?

• Welke organisaties kennen jullie die hier een rol bij zouden willen spelen?

• Meer richten op software voor vullen van Infobox (tekst analyse, zie
  bijvoorbeeld Ipopulator)

• Wat te doen met dialecten bijv. Fries?

• Zouden we ons niet moeten concentreren op specifieke informatie?

• WIE DOET MEE?

  • 6. En verder nog meer algemene mapping’s: • Images. Links pointing at Wikimedia Commons images depicting a resource are extracted and represented by using the foaf:depiction property. • Redirects. In order to identify synonymous terms, Wikipedia articles can redirect to other articles. We extract these redirects and use them to resolve references between DBpedia resources. • External links. Articles contain references to external Web resources which we represent by using the DBpedia property dbpedia:reference. • Pagelinks. We extract all links between Wikipedia articles and represent them by using the dbpedia:wikilink property. • Homepages. This extractor obtains links to the homepages of entities such as companies and organisations by looking for the terms homepage or website within article links • Categories. Wikipedia articles are arranged in categories, which we represent by using the SKOS vocabulary4. • Geo-coordinates. The geo-extractor expresses coordinates by using the Basic Geo (WGS84 lat/long) Vocabulary5 and the GeoRSS Simple encoding of the W3C Geospatial Vocabulary6. • Metainformation. A new extractor which introduces organisational properties like direct edit links and oai identifiers for edit and delete operations.

  • 16. discussie • Goed idee? • Gaat het werken via de community? Hoe moeten we dit opstarten? • Welke organisaties kennen jullie die hier een rol bij zouden willen spelen? • Meer richten op software voor vullen van Infobox (tekst analyse, zie bijvoorbeeld Ipopulator) • Wat te doen met dialecten bijv. Fries? • Zouden we ons niet moeten concentreren op specifieke informatie? • WIE DOET MEE?
