Jarrar: The Next Generation of the Web 3.0: The Semantic Web Vesion
2 likes905 views
This document discusses notes from a lecture on the Semantic Web and Web 3.0. It introduces the Semantic Web vision of adding semantic meaning to web pages so search results can be based on meaning rather than just string matching. An example is given of searching for a developer job within 10 minutes of Ramallah, and how current search returns bad results, whereas semantic search could provide better, more meaningful results by understanding data embedded in web pages. The document outlines the Semantic Web concept of a web of linked data that can be processed by machines, as well as the W3C definition and goals of encouraging semantic content and conversion of the web to a web of data through meaningful relations between things.

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".
