Retrieval takes place in a semantic co-ordinate system presented by information visualisation maps.
And even the users will contribute to these repositories by communicating their experiences to other users who follow their footsteps. Navigating the Web should allow people to leave pointers for those who might also navigate along the same paths. The growth of the Internet and the inherent volatility of complex information spaces require a new model of software. By this dynamic trait only a system of software agents can react adequately to changes in large, complex, and volatile informaio saces. One part of these Information Agents enables users to navigate the Web within a semantic coordinate system that provides them with orientation.
