Visualization and Analysis of Associated Information

Technical Description:

A computer program has been developed that is an aid for visualizing and sorting linked data. As a network analysis tool, this offers the capability to keep track of associations and communications among many entities.

This program provides the means to display associations in an intuitive, graphical manner. The ranking of entities and linkages, based on their apparent importance in association networks, is easily accomplished with the results displayed graphically. Users can also retrieve text (even in foreign scripts), sound, and pictures associated with the data. Background text can be searched, analyzed for content, and automatically labeled (in any language). The retrieved information, as well as graphical displays, can be pasted into word processing and graphics programs to make reports and viewgraphs.

Linkage diagrams can be arranged with an array of automatic and manual tools. Displays can be overlaid with maps and charts and other annotation. Temporal linkages may be animated for studying communication patterns, and activity information can be plotted in a variety of formats.

The program provides a delightfully friendly and efficient user interface offering more than 150 menu commands, extensive user customization, and multiple screen support. User documentation and samples files are available. A U.S. Patent application has been filed.
