What is this Article about? Extreme Summarization with Topic-aware Convolutional Neural Networks
Table 7: Proportion of novel n-grams in summaries generated by various models on the XSum test set.
['Models', '% of novel n-grams in generated summaries', '% of novel n-grams in generated summaries', '% of novel n-grams in generated summaries', '% of novel n-grams in generated summaries']
S6SS1SSS0Px2 How Abstractive are the Generated Summaries? We further assessed the extent to which various models are able to perform rewriting by generating genuinely abstractive summaries. We omit extractive systems (lead and ext-oracle) as they are not capable of generating summaries from scratch with novel n-grams.
