ÚFAL at MRP 2020: Permutation-invariant Semantic Parsing in PERIN
David Samuel, Milan Straka · 2020
We present PERIN, a novel permutationinvariant approach to sentence-to-graph semantic parsing.PERIN is a versatile, crossframework and language independent architecture for universal modeling of semantic structures.Our system participated in the CoNLL 2020 shared task, Cross-Framework Meaning Representation Parsing (MRP 2020), where it was evaluated on five different frameworks (AMR, DRG, EDS, PTG and UCCA) across four languages.PERIN was one of the winners of the shared task.The source code and pretrained models are available at http://www. github.com/ufal/perin.
