TUPA at MRP 2019: A Multi-Task Baseline System
Daniel Hershcovich, Ofir Arviv · 2019
This paper describes the TUPA system submission to the shared task on Cross-Framework Meaning Representation Parsing (MRP) at the 2019 Conference for Computational Language Learning (CoNLL).TUPA provides a baseline point of comparison and is not considered in the official ranking of participating systems.While originally developed for UCCA only, TUPA has been generalized to support all MRP frameworks included in the task, and trained using multi-task learning to parse them all with a shared model.It is a transition-based parser with a BiLSTM encoder, augmented with BERT contextualized embeddings.
