Abstract: Computer software and a user interface for information management are provided in which semantic networks may be entered and analyzed. The user interface for entry of the semantic network uses a windows environment to enter the nodes and the arcs connecting the nodes. Arcs may serve as sources or destinations for other arcs. The software includes a first data structure relating to the structure of the semantic network and a second data structure relating to the display of the semantic network. Additional data structures may be used to show the semantic network in group, table, and other forms. Two illustrative applications are described for Internet Management and Resource Management.
