The DBpedia project provides Linked Data identifiers for currently 2.6 million things and serves a large knowledge base of structured information. DBpedia developed into the central interlinking hub for the Linking Open Data project, its URIs are used within named entity recognition services such as OpenCalais and annotation services such as Faviki, and the BBC started using DBpedia as their central semantic backbone. DBpedia's structured data serves as background information in the process interlinking datasets and provides a rich source of information for application developers. Beside making the DBpedia knowledge base available as linked data and RDF dumps, we offer a Lookup Service which can be used by applications to discover URIs for identifying concepts, and a SPARQL endpoint that can be retrieve data from the DBpedia knowledge base to be used in applications. This talk will give an introduction to DBpedia for web developers and an overview of DBpedia's development over the last year. We will demonstrate how DBpedia URIs are used for document annotation and how Web applications can via DBpedia facilitate Wikipedia as a source of structured knowledge.
