DeepCx: A transition-based approach for shallow semantic parsing with complex constructional triggers
Jesse Dunietz, Jaime R. Carbonell, Lori S. Levin · 2018
This paper introduces the SURFACE CON-STRUCTION LABELING (SCL) task, which expands the coverage of Shallow Semantic Parsing (SSP) to include frames triggered by complex constructions.We present DeepCx, a neural, transition-based system for SCL.As a test case for the approach, we apply DeepCx to the task of tagging causal language in English, which relies on a wider variety of constructions than are typically addressed in SSP.We report substantial improvements over previous tagging efforts on a causal language dataset.We also propose ways DeepCx could be extended to still more difficult constructions and to other semantic domains once appropriate datasets become available.
