Information Triage with TRIST

TRIST ("The Rapid Information Scanning Tool") is the information retrieval and triage component for the analytical environment called nSpace. TRIST uses Human Information Interaction (HII) techniques to interact with massive data in order to quickly uncover the relevant, novel and unexpected. TRIST provides query planning, rapid scanning over thousands of search results in one display, and includes multiple linked dimensions for result characterization and correlation. It also forms a cohesive platform for integrating computational linguistic capabilities such as entity extraction, document clustering and other new techniques. Analysts work with TRIST to triage their massive data and to extract information into the Sandbox evidence marshalling environment. Initial experiments with TRIST show that analyst work product quality is increased, in half the time, while reading double the documents.
