The semantic web: a brain for humankind

Originally, the computer was intended as a device for computation. Then, in the 1980s, the PC developed into a system for games, text processing, and PowerPoint presentations. Eventually, the computer became a portal to cyberspace—an entry point to a worldwide network of information exchange and business transactions. Consequently, technology that supports access to unstructured, heterogeneous, and distributed information and knowledge sources is about to become as essential as programming languages were in the 60s and 70s.
