Network visualization and navigation

摘要

A display manager allows for visualization and navigation of a semantic network via an interactive graphical user interface. The display manager accesses a semantic network model defining relationships amongst nodes in the semantic network. Given a portion of the semantic network, the display manager renders a radial perspective to represent the node relationships in the given portion of the semantic network. The radial perspective includes a centered node, around which other displayed nodes and relationships are substantially concentrically arranged. To navigate to and view a different portion of the semantic network, the display manager allows the user to select nodes currently displayed in the radial perspective. In response to selection of one or more nodes, the display manager updates the radial perspective to represent nodes and node relationships from a different portion of the semantic network with the user-selected node as a new center node.
