Cross-lingual Semantic Representation for NLP with UCCA: Tutorial at COLING 2020

Omri Abend, Dotan Dvir, Daniel Hershcovich, Jakob Prange and Nathan Schneider

This is an introductory tutorial to UCCA (Universal Conceptual Cognitive Annotation), a cross-linguistically applicable framework for semantic representation, with corpora annotated in English, German and French, and ongoing annotation in Russian and Hebrew. UCCA builds on extensive typological work and supports rapid annotation. The tutorial provides a detailed introduction to the UCCA annotation guidelines, design philosophy and the available resources; and a comparison to other meaning representations. It also surveys the existing parsing work, including the findings of three recent shared tasks, in SemEval and CoNLL, that addressed UCCA parsing. Finally, the tutorial presents recent applications and extensions to the scheme, demonstrating its value for natural language processing in a range of languages and domains.

The tutorial was presented at COLING 2020. All contents are available in this repository, including the abstract, slides and recorded presentations.
