Exploratory Visual Analysis of Intelligence Reports

We are developing a system that will help analysts browse through large collections of intelligence reports. The system begins by parsing plain text reports and constructing XML nodes with fields for the important report items such as people mentioned, dates, places, and activities. From there, we construct a graph visualization of the reports with a node for each report and for all of the entities in a report (see figure). Specific colors represent the different types of entities. Entities appear only once, so it is possible to see ones that are mentioned in multiple reports. We continue to work on interactive capabilities in the system so that viewers can pose various kinds of queries and see the results indicated visually. Additionally, we are working on alternative representations of the reports that do not use a traditional graph visualization. This work is led by John Stasko.
