1. Towards the Linked Data Web Sören Auer

2. Problem: Try to search for these things on the current Web: Apartments near German-Russian bilingual childcare in Leipzig. ERP service providers with offices in Vienna and London. Researchers working on multimedia topics in Eastern Europe. Informationis available on the Web, but opaque to current Web search. Why Linked Open Data? Solution: complement text on Web pages with structured linked open data & intelligently combine/integrate such structured information from different sources: Search engine HTML HTML RDF RDF Web server Web server Web server Web server berlin.de Has everything about childcare in Berlin. Immobilienscout.de Knows all about real estate offers in Germany DB DB
