IN-SPIRE™ Visual Document Analysis is a "discovery tool" that "integrates information visualization with interaction and query capabilities." [1]

How It Works

"IN-SPIRE™ can quickly and automatically convey the gist of large sets of unformatted text documents such as technical reports, web data, newswire feeds and message traffic. By clustering similar documents together, this Windows-based software unveils common themes and reveals hidden relationships within the collection. IN-SPIRE™ allows analysts to spend more time exploring the information they find most relevant and less time sifting through the masses of irrelevant documents.

"IN-SPIRE™ could be used to analyze threats to homeland security, for example. It automatically analyzes a multitude of text files and determines key topics or themes in each, and creates a signature for each document in the collection. IN-SPIRE’s two visualizations display representations of the documents so those with similar or related topics appear closer together. The Galaxy visualization uses the metaphor of the stars in the night sky with each star representing individual documents. The ThemeView™ visualization uses a 3-dimensional terrain map display to provide a high-level overview of the data." [2]
