What is this Article about? Extreme Summarization with Topic-aware Convolutional Neural Networks
Table 4: Performance of extractive baselines on CNN, DailyMail, NY Times, Newsroom, and XSum datasets. We report ROUGE scores for the lead baseline and ext-oracle, the extractive oracle system. All results are computed on the test set.
['Datasets', 'lead', 'lead', 'lead', 'ext-oracle', 'ext-oracle', 'ext-oracle']
The lead baseline performs extremely well on CNN, DailyMail, NY Times and Newsroom confirming that they contain fairly extractive summaries. ext-oracle further shows that improved sentence selection would bring further performance gains to extractive approaches. Interestingly, lead and ext-oracle perform poorly on XSum underlying the fact that it contains genuinely abstractive summaries.
