详细介绍
The task of AMR-to-text generation is to generate grammatical text that
sustains the semantic meaning for a given AMR graph. We at- tack the task by
first partitioning the AMR graph into smaller fragments, and then generating
the translation for each fragment, before finally deciding the order by solving
an asymmetric generalized traveling salesman problem (AGTSP). A Maximum Entropy
classifier is trained to estimate the traveling costs, and a TSP solver is used
to find the optimized solution. The final model reports a BLEU score of 22.44
on the SemEval-2016 Task8 dataset.
