Modeling Graph Structure in Transformerfor Better AMR-to-Text Generation
Table 4: Performance on the test set of our approach with or without modeling structural information of indirectly connected concept pairs.
['[BOLD] System', '[BOLD] BLEU']
It shows that by modeling structural information of indirectly connected concept pairs, our approach improves the performance on the test set from 29.92 to 31.82 in BLEU scores. It also shows that even without modeling structural information of indirectly connected concept pairs, our approach achieves better performance than the baseline.
