I will discuss what makes AMR abstract, comparing it with syntactic structures as they are annotated in the treebanks. I will also discuss how similar ideas can be implemented in the alignment of parallel parse trees, sharing our experience working on a hierarchically aligned Chinese-English parallel treebank. Finally I will speculate on the relative strengths and weaknesses of these two types of resources and the MT approaches they support.
