Chinese Poetry Generation with a Salient-Clue Mechanism
Table 3: Saliency selection results. Random: randomly select K characters for three times and use the average Jaccard values. tf-idf: directly select K characters in terms of tf-idf, without SC.
['[BOLD] Models', '[ITALIC]  [BOLD] Wujue', '[ITALIC]  [BOLD] Qijue']
tfidf-SSal achieves about 50% overlap of human-selected salient characters, which is notably higher than Random and tf-idf. With only attention values, naive-TopK performs worse than tf-idf on Wujue. Combining tf-idf and SSal makes notable improvement.
