Web 3.0

Are you ready?

W3C Semantic Web Logo Web 3.0 is widely seen the natural evolution of Web 2.0.  As the Web has grown and changed so have the technologies that define it. Web 1.0 served web pages to the user with no other interaction, other than reading the pages themselves.  Web 2.0 offers interactivity through software applications which enable users to collaborate across platforms. This is evidenced with social media sites such as Facebook and Twitter among others.   Mobile technology, streaming media, cloud based applications all affect how we access and use the internet.  Web 3.0 is the next step in the evolution of the Web and how we will use it in the future.  One of Web 3.0’s defining features is the Semantic Web which will implement the classifying and storing of information read and understood by both machines and humans.

What does the Semantic Web do?  It provides a common framework which permits the sharing and reusing of data over platforms and applications. Web 3.0 is still evolving but holds promise as a platform where automated software will be able to save, transmit, and apply information which is machine readable and can be sent throughout the web. The phrase “Semantic Web” was named by Tim Berners-Lee, who is the inventor of the World Wide Web and director of the W3C also known as the World Wide Web Consortium, which he founded in 1994.  Berners-Lee describes the Semantic Web as  "a web of data that can be processed directly and indirectly by machines."  The W3C is responsible for the creation of the Semantic Web standards which are based on the W3C’s Resource Description Framework, a metadata data model, a language structured for data, and widely used as a means for describing web resources.

The idea of the Semantic Network Model was created by Allan M. Collins, M. Ross Quillian and Elizabeth F. Loftus to cover information that was structured semantically.  The network of web pages which are hyperlinked and human-readable (documents) is extended when  metadata that is machine-readable (data) is added. Web 3.0 will allow automated agents (bots) to search and read information and execute various tasks on the user’s part, in a more efficient and logical manner throughout the web.  The use of the Semantic Web and its applications is most evident in business or scientific research, and other fields that employ technologies which necessitate the sharing and transmitting of data across domains.
