On Visualization of Cocitation Networks

The visualization of a cocitation network is a useful technique for information scientists. The technique will help to illustrate the intellectual structure of a given knowledge domain. We hope our results will improve on current tools with regard to user interface interactivity and scale better for larger data sets. We developed a tool, with the visualizing cocitation network in mind, by using an open-sourced toolkit for interactive information visualization to address some of these inadequacies. This tool exhibits cocitation graphs with latent visual cues and allows direct interaction with the visualized graphs. We demonstrated the visualized effects of this tool and complemented the results with its domain content analysis in a case study.
