6. How it all started
- 2006 - Sören Auer (busy with his PhD) asking people: “Wikipedia fact
tables look like triples, don’t you want to write some extractor?”
- 6 months later: Sören wrote the extractor himself and asked Jens
Lehmann to help with writing a paper
- Chris Bizer : “We are extracting people and place information from
Wikipedia too – lets join efforts and call it DBpedia.”
- Kingsley Idehen: “I need a showcase for my Virtuoso triple store.”

compete for the best quality (in a certain
language)
- Need to define the interface (help needed)

17. Every Enterprise needs its DBpedia
- Represent common sense knowledge (DBpedia and
other LOD datasets) as well as the specific enterprise
knowledge

addition to SOA facilitating enterprise-wide data linking
& integration
