Detecting Post-Edited References and Their Effect on Human Evaluation

no code implementations EACL (HumEval) 2021 Věra Kloudová, Ondřej Bojar, Martin Popel

This paper provides a quick overview of possible methods how to detect that reference translations were actually created by post-editing an MT system.

CorefUD 1.0: Coreference Meets Universal Dependencies

no code implementations LREC 2022 Anna Nedoluzhko, Michal Novák, Martin Popel, Zdeněk Žabokrtský, Amir Zeldes, Daniel Zeman

Recent advances in standardization for annotated language resources have led to successful large scale efforts, such as the Universal Dependencies (UD) project for multilingual syntactically annotated data.

Do UD Trees Match Mention Spans in Coreference Annotations?

no code implementations Findings (EMNLP) 2021 Martin Popel, Zdeněk Žabokrtský, Anna Nedoluzhko, Michal Novák, Daniel Zeman

One can find dozens of data resources for various languages in which coreference - a relation between two or more expressions that refer to the same real-world entity - is manually annotated.

CUNI Submission in WMT22 General Task

no code implementations29 Nov 2022 Josef Jon, Martin Popel, Ondřej Bojar

We evaluate performance of MBR decoding compared to traditional mixed backtranslation training and we show a possible synergy when using both of the techniques simultaneously.


Understanding Model Robustness to User-generated Noisy Texts

1 code implementation WNUT (ACL) 2021 Jakub Náplava, Martin Popel, Milan Straka, Jana Straková

We also compare two approaches to address the performance drop: a) training the NLP models with noised data generated by our framework; and b) reducing the input noise with external system for natural language correction.
