Task: Question Answering
Input (English): For evaluation metrics, we used BLEU BIBREF8 and RIBES BIBREF9 to measure translation accuracy, and token-level delay to measure latency. We used Kytea BIBREF10 as a tokenize method for evaluations of Japanese translation accuracy. 
 Question: Which metrics do they use to evaluate simultaneous translation?
Output (English): BLEU BIBREF8 RIBES BIBREF9 token-level delay
