  3. What is the Web of Data? • Current web is a network that links pages: Web of Pages • Can be searched/browsed with a traditional web browser • Links connect pages • Data network has emerged inside the web: Web of Data • Can be searched/browsed with a semantic application • Links connect information (e.g., parrot → bird) • New (semantic) web consists of both of the networks Web of Pages WWW • Web of Pages (for humans): World Wide Web Web of Data • Web of Data (for machines): Giant Global Graph GGG
