Semantic Web: Intro
The document introduces the semantic web, which extends the current web by giving information well-defined meaning so that computers and people can better cooperate. It defines the semantic web and discusses its key components, including URIs, ontologies, linked open data, RDF, OWL, SPARQL, and open world reasoning. Examples of semantic web use cases include data.gov, DBPedia, Google Recipes, and Facebook's implementation using RDFa.
