Task: Summarization
Input (English): We  propose an  interactive  classification approach  for natural  language  queries. Instead of classifying given the natural language query only, we ask the user for additional information using a sequence of binary and multiple-choice questions. At each turn, we use a policy controller to decide if to present a question or pro-vide the user the final answer, and select the best question to ask by maximizing the system information gain. Our formulation enables bootstrapping the system without any interaction data, instead relying on non-interactive crowdsourcing an-notation tasks. Our evaluation shows the interaction helps the system increase its accuracy and handle ambiguous queries, while our approach effectively balances the number of questions and the final accuracy.
Output (English): We propose an interactive approach for classifying natural language queries by asking users for additional information using information gain and a reinforcement learning policy controller.
