Need for Semantic Web Need for Semantic Web

“The Semantic Web: … content that is meaningful to computers [and that] will unleash a revolution of new possibilities … Properly designed, the Semantic Web can assist the evolution of human knowledge …”

(Tim Berners-Lee, …, Weaving the Web)

The semantic web will make it possible for machines to know the difference!

** Edgar F. Codd and C. J. Date are famous in the area of databases for defining levels of normal forms

Real Problem Real Problem

A person decides to do family history research for the first time

  • n their Danish family lines.
  • Where do they go?
  • What records do they look for?
  • How do they handle records in Danish?
  • How can they tell when the records they have match their

search family?

Semantic Web Semantic Web Ideal for Family History Ideal for Family History

SOLUTION – PROTOTYPE

 The heart of a one-stop web site for naïve

researchers

 So many records have been extracted into

digitized forms and are often available on the Web

 Limited geographically – parish and probate

records from Nim District, Skanderborg, Denmark

  • 100% probates

100% probates

  • 100% marriages
