Title The New Propbank: Aligning Propbank with AMR through POS Unification
Authors Tim O'Gorman, Sameer Pradhan, Martha Palmer, Julia Bonn, Kathryn Conger and James Gung
Abstract We present a corpus which converts the sense labels of existing Propbank resources to a new unified format which is more compatible with AMR and more robust to sparsity. This adopts an innovation of the Abstract Meaning Representation project(Banarescu et al. 2013) in which one abstracts away from different, related parts of speech, so that related forms such as "insert" and "insertion" could be represented by the same roleset and use the same semantic roles. We note that this conversion also serves to make the different English Propbank corpora released over the years consistent with each other, so that one might train and evaluate systems upon that larger combined data. We present analysis of some appealing characteristics of this final dataset, and present preliminary results of training and evaluating SRL systems on this combined set, to spur usage of this challenging new dataset.
