Knowledge representation, the World Wide Web, and the evolution of logic

Computer networks are nearly as old as computers themselves. However, prior to the Internet — the infrastructure of the Web — such networks were all closed: only designated computers — within the same business or organization — were able to join and, typically, each network had strict control over the sorts of information would be exchanged on the network and in what forms. Perhaps the most significant feature of the Web is that it is open, indeed radically so. Unlike closed networks, the Internet is accessible to a huge segment of the world’s population, and to publish virtually any content, one needs only access to a web server.
