Digital Reasoning Systems, a software company in Franklin, Tenn., is working with undisclosed U.S. government agencies to deliver a Cassandra-based system for intelligence-related applications–such as looking for suspicious terms and connections between people in huge quantities of documents in a variety of formats, including Word documents and transcripts of recordings of phone calls, says Dave Danielson, its vice president of marketing. “They have some problems in finding bad guys in hundreds of millions of documents,” he says. Digital Reasoning’s own software helps store and categorize such unstructured information in Cassandra, using the technology to help narrow down searches that might pull up millions of documents into the ten to thirty or so that human analyst need to look at, Danielson says.
