Robust Incremental Neural Semantic Graph Parsing
Table 2: DMRS development set results of encoder-decoder models with pointer-based alignment prediction, delexicalized predicates and hard or soft attention.
['Model', 'EDM', 'EDM [ITALIC] P', 'EDM [ITALIC] A']
The results show that the arc-eager models performs better than those based on top-down representation. For the arc-eager model we use hard attention, due to the natural interpretation of the alignment prediction corresponding to the transition system. The stack-based architecture gives further improvements.
