abstract meaning representation

Abstract Meaning Representation Parsing is being done at
SemEval again this year, but this time the stakes are higher and the challenge greater. Generation from AMR is a brand new task at SemEval and the stakes are, well, just as high.
In the first subtask, given a sentence of biomedical English text, parsing systems
will attempt to produce an accurate semantic interpretation, as
represented by the AMR standard. In the second subtask, given an AMR representing a sentence of plain Englihs, generation systems will attempt to recover that sentence.

Abstract Meaning Representation Parsing is a new shared task at
SemEval this year. Given a sentence of plain English text, systems
