DBpedia

DBpedia is a community-driven project that extracts structured data from Wikipedia and publishes it on the Semantic Web. It was created with many hours of volunteer work.

• Purpose: turn Wikipedia’s infoboxes and structured content into a knowledge graph of linked data.
• Namespaces:
  • dbr:: DBpedia Resources (individual entities).
    • Example: dbr:Barack_Obama
  • dbo:: DBpedia Ontology (classes and properties).
    • Example: dbo:Person
• Technology stack: built on RDF, RDFS, and OWL, with values typed using XSD.
• Example triple:

dbr:Barack_Obama dbo:spouse dbr:Michelle_Obama

• Links:
  • DBpedia Resources link to external datasets using owl:sameAs.
  • Schema.org concepts are often mapped to equivalent DBO classes.
