The Knowledge Web may be regarded as a sophisticated graph that contains all information on a certain subject. Consider the sample visualization of the knowledge web shown in figure 1. The subject being talked about is Biology. The Knowledge Web contains several topics, each represented by an oval object. The objects are colored to indicate that they belong to some category. There are two kinds of connections shown in this Knowledge Web. This can be extended to include more kinds of connections. The connections can also be colored differently. The subject may contain several topics. These topics are depicted by means of `Knowledge Nodes. Each Knowledge Node contains Information Elements, which are hyperlinks to varied pieces of information. These pieces of information may be located anywhere on the World Wide Web. They may constitute different forms of multimedia like a definition(text or HTML), a video-clip, an image or animation, or even a simulation. ``A picture is worth a thousand words''. It is far easier to understand a topic when it is explained with pictures than with several pages of text. A teacher may have information about a certain topic in various forms of multimedia. The Knowledge Web enables her to integrate them all into a single presentation. It integrates all the information into a single presentation. all the information she has in various convenient multimedia forms. Connections are drawn between two or more knowledge nodes to show that some form of relationship exists between the topics represented by them. The connections are not mere lines. The difference is that they move when the knowledge nodes they connect are moved, while the lines remain static.
