We present the SemEval 2019 shared task on Universal Conceptual Cognitive Annotation (UCCA) parsing in English, German and French, and discuss the participating systems and results.UCCA is a crosslinguistically 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.The shared task has yielded improvements over the state-of-the-art baseline in all languages and settings.Full results can be found in the task's website https://competitions. codalab.org/competitions/19160.
