Cross-lingual Learning of an Open-domain Semantic Parser

Abstract

We propose a method for learning semantic CCG parsers by projecting annotations via a parallel corpus. The method opens an avenue towards cheaply creating multilingual semantic parsers mapping open-domain text to formal meaning representations. A first cross-lingually learned Dutch (from English) semantic parser obtains f-scores ranging from 42.99\% to 69.22\% depending on the level of label informativity taken into account, compared to 58.40\% to 78.88\% for the underlying source-language system. These are promising numbers compared to state-of-the-art semantic parsing in open domains.
