The Semantic Web
• The term was coined by Tim Berners-Lee for a web of data that can be
processed and understood by machines.
• In 2001, An article in Scientific American by Berners-Lee, Hendler, and
Lassila described an expected evolution of the Web to a Semantic Web.
• W3C: "The Semantic Web provides a common framework that allows
data to be shared and reused across application, enterprise, and
community boundaries.”
• Encourage the inclusion of semantic content in web pages, converting
the current web, dominated by unstructured and semi-structured
documents into a "web of data".
