SemEval 2019 Shared Task: Cross-lingual Semantic Parsing with UCCA - Call for Participation
This is an incremental effort that calls for participation in a competition to improve UCCA parsing, benefiting applications relying on semantic evaluation.
The paper announces a shared task for UCCA parsing in English, German, and French, aiming to advance semantic parsing by addressing challenges like reentrancy and discontinuous structures, with expected contributions to both UCCA-specific and general semantic parsing methods.
We announce a shared task on UCCA parsing in English, German and French, and call for participants to submit their systems. UCCA is a cross-linguistically applicable framework for semantic representation, which builds on extensive typological work and supports rapid annotation. UCCA poses a challenge for existing parsing techniques, as it exhibits reentrancy (resulting in DAG structures), discontinuous structures and non-terminal nodes corresponding to complex semantic units. Given the success of recent semantic parsing shared tasks (on SDP and AMR), we expect the task to have a significant contribution to the advancement of UCCA parsing in particular, and semantic parsing in general. Furthermore, existing applications for semantic evaluation that are based on UCCA will greatly benefit from better automatic methods for UCCA parsing.
