For the CNN-Dailymail dataset, the Lead-3 model is considered a strong baseline; both the abstractive BIBREF16 and extractive BIBREF14 state-of-the art methods on this dataset beat this baseline only marginally. For the proxy report section of the AMR bank, we consider the Lead-1-AMR model as the baseline. 
 Question: Which other methods do they compare with?
Lead-3 Lead-1-AMR
