Factorising AMR generation through syntax (N19-1)

Copied to clipboard

Challenge: Abstract Meaning Representation (AMR) is a semantic annotation framework which abstracts away from the surface form of text to capture the core 'who did what to whom' structure.
Approach: They propose to decompose the generation process into two steps: first generate a syntactic structure, and then generate the surface form.
Outcome: The proposed approach generates meaning-preserving syntactic paraphrases of the same graph, as judged by humans.
