The semantic web is a term used to describe a web that is as easily read and accessed by a computer as by a human. In order for this to happen, websites and applications must be written in, and store data using, correctly applied programming languages, data structures, and data categories. This work is being spearheaded by the World Wide Web Consortium (W3C). As the semantic web expands, computers can use data on the web as the basis for evolving artificial intelligence.
