Query: ShanghaiTech at MRP 2019: Sequence-to-Graph Transduction with
  Second-Order Edge Inference for Cross-Framework Meaning Representation
  Parsing   This paper presents the system used in our submission to the \textit{CoNLL
2019 shared task: Cross-Framework Meaning Representation Parsing}. Our system
is a graph-based parser which combines an extended pointer-generator network
that generates nodes and a second-order mean field variational inference module
that predicts edges. Our system achieved \nth{1} and \nth{2} place for the DM
and PSD frameworks respectively on the in-framework ranks and achieved \nth{3}
place for the DM framework on the cross-framework ranks.
