Table 2: BLEU scores at different retention rates under three ordering (sentence length here is system output sentence length; source sentence length behaves the same).
['Retention', 'Sentence length', 'Random referral', 'BLEUVar']
We further extended the experiment design and added a naive baseline which simply looks at the sentence length to reject sentences (ordering test data using sentence_lengthlongest_sentence_length, i.e. from short sentences to long sentences). In fact, the performance of sentence length referral is worse than another naive baseline: randomly referring sentences without looking at them at all.
