Learning Sentence Embeddings for Coherence Modelling and Beyond
Table 3: ROUGE scores on the CNN/DailyMail summarization task. Our PPD-based heuristic outperforms the suite of established heuristic summarizers. However, the higher performance of the deep-learning models demonstrates that training explicitly for summarization is beneficial.
['[BOLD] Model (lead baseline source)', '[BOLD] ROUGE-1', '[BOLD] ROUGE-2', '[BOLD] ROUGE-L']
We observe that our model has ROUGE scores superior to the other heuristic approaches by a margin of approximately 2 points for ROUGE-1 and -L and 1 point for ROUGE-2. In contrast, the deep-learning approaches trained explicitly for summarization achieve even higher scores, suggesting that there is more to a good summary than the sentences simply being introductory-like.
