Before revision:  Our approach includes (1) learning query-agnostic phrase representations via question generation and distillation; (2) novel negative-sampling methodsfor global normalization; (3) query-side fine-tuning for transfer learning .
After revision:  We present an effective method to learn phrase representations from the supervision of reading comprehension tasks, coupled with novel negative sampling methods. We also propose a query-side fine-tuning for transfer learning .
