  • Information retrieval system
    Patent number: 7165070
    Abstract: A method of retrieving information by navigating within a web browsing session. The information is stored on a server in a hierarchical tree comprising a root node, top-level child nodes representing information categories and leaf nodes representing information sub-categories. Each of the nodes has an associated information unit. Initially, an information unit associated with the root node is displayed in an information space. A user then performs navigation operations from the root node, by selecting a first top-level child node, traversing the leaf nodes and selecting a first leaf node. A first information unit associated with the first leaf node is subsequently displayed in the information space. This first information unit is stored, the navigation operations are repeated on a second top-level child node until a second information unit is displayed in the information space.
