We present a new approach to learning semantic parsers from multiple datasets, even when the target semantic formalisms are drastically different, and the underlying corpora do not overlap. We handle such "disjoint" data by treating annotations for unobserved formalisms as latent structured variables. Building on state-of-the-art baselines, we show improvements both in frame-semantic parsing and semantic dependency parsing by modeling them jointly. Our code is open-source and available at https://github.com/ Noahs-ARK/NeurboParser.
In addition, REF present a multi-task approach for frame-semantic parsing and semantic dependency parsing with latent structured variables.
