Orange @ UMR Parsing Shared Task

Abstract

Uniform Meaning Representation (UMR) is a novel meaning representation formalism emanating from Abstract Meaning Representation (AMR). Since it is more complex than AMR, including document level annotation it is more difficult to create a parsing pipeline which can predict an UMR document from a set of consecutive sentences. The UMR Parsing Shared Task was created to compare different approaches. We decided to use a 2-step approach to predict sentence level and document level annotation. Since the available data was limited, we opted for a multilingual model, even though unlike AMR, in UMR the concepts of the meaning graph are not drawn from a single source, but from language dependend resources. Our final score was 19.35%, 0.08 points behind the best participant (19.43%).
