FERRET: Interactive Question-Answering for Real-World Environments 
 
 This paper describes FERRET , an interactive question-answering (Q/A) system designed to address the challenges of integrating automatic Q/A applications into real-world environments. FERRET utilizes a novel approach to Q/A known as predictive questioning which attempts to identify the questions (and answers ) that users need by analyzing how a user interacts with a system while gathering information related to a particular scenario.
