Findings of the WMT 2020 Shared Task on Quality Estimation

no code implementations WMT (EMNLP) 2020 Lucia Specia, Frédéric Blain, Marina Fomicheva, Erick Fonseca, Vishrav Chaudhary, Francisco Guzmán, André F. T. Martins

We report the results of the WMT20 shared task on Quality Estimation, where the challenge is to predict the quality of the output of neural machine translation systems at the word, sentence and document levels.

Revisiting Higher-Order Dependency Parsers

no code implementations ACL 2020 Erick Fonseca, Andr{\'e} F. T. Martins

Neural encoders have allowed dependency parsers to shift from higher-order structured models to simpler first-order ones, making decoding faster and still achieving better accuracy than non-neural parsers.


Findings of the WMT 2019 Shared Tasks on Quality Estimation

no code implementations WS 2019 Erick Fonseca, Lisa Yankovskaya, Andr{\'e} F. T. Martins, Mark Fishel, Christian Federmann

We report the results of the WMT19 shared task on Quality Estimation, i. e. the task of predicting the quality of the output of machine translation systems given just the source text and the hypothesis translations.

Portuguese Word Embeddings: Evaluating on Word Analogies and Natural Language Tasks

3 code implementations WS 2017 Nathan Hartmann, Erick Fonseca, Christopher Shulby, Marcos Treviso, Jessica Rodrigues, Sandra Aluisio

Word embeddings have been found to provide meaningful representations for words in an efficient way; therefore, they have become common in Natural Language Processing sys- tems.
