• System allowed full text searching on both structured and unstructured data. Important text went through an entity extraction and geocoding process. The system allowed for faceted searches as well as fuzzy queries to find the same entities across the multiple datasets. Geospatial queries such as “give me all documents within a half a mile of 123 Fake Street, Arlington VA” were also possible.
• Created word stat charting program using JFreeChart to help users find the most common or uncommon words across multiple documents. The purpose was to allow the user a quick categorization of whatever documents they were reading.

• Created a “nexus finder” that gave an overview of all the People, SSNs, and Addresses associated with a person. The program would search multiple levels to find harder to find relationships between tax avoiders. The generated Neo4j network was visualized in Gephi for link analysis.
