gaBERT — an Irish Language Model

no code implementations LREC 2022 James Barry, Joachim Wagner, Lauren Cassidy, Alan Cowap, Teresa Lynn, Abigail Walsh, Mícheál J. Ó Meachair, Jennifer Foster

We compare our gaBERT model to multilingual BERT and the monolingual Irish WikiBERT, and we show that gaBERT provides better representations for a downstream parsing task.

Naive Bayes versus BERT: Jupyter notebook assignments for an introductory NLP course

no code implementations NAACL (TeachingNLP) 2021 Jennifer Foster, Joachim Wagner

We describe two Jupyter notebooks that form the basis of two assignments in an introductory Natural Language Processing (NLP) module taught to final year undergraduate students at Dublin City University.

Revisiting Tri-training of Dependency Parsers

2 code implementations EMNLP 2021 Joachim Wagner, Jennifer Foster

We compare two orthogonal semi-supervised learning techniques, namely tri-training and pretrained word embeddings, in the task of dependency parsing.

The DCU-EPFL Enhanced Dependency Parser at the IWPT 2021 Shared Task

1 code implementation ACL (IWPT) 2021 James Barry, Alireza Mohammadshahi, Joachim Wagner, Jennifer Foster, James Henderson

The task involves parsing Enhanced UD graphs, which are an extension of the basic dependency trees designed to be more facilitative towards representing semantic structure.

The ADAPT Enhanced Dependency Parser at the IWPT 2020 Shared Task

2 code implementations WS 2020 James Barry, Joachim Wagner, Jennifer Foster

Unfortunately, we did not ensure a connected graph as part of our pipeline approach and our competition submission relied on a last-minute fix to pass the validation script which harmed our official evaluation scores significantly.

Treebank Embedding Vectors for Out-of-domain Dependency Parsing

1 code implementation ACL 2020 Joachim Wagner, James Barry, Jennifer Foster

A recent advance in monolingual dependency parsing is the idea of a treebank embedding vector, which allows all treebanks for a particular language to be used as training data while at the same time allowing the model to prefer training data from one treebank over others and to select the preferred treebank at test time.

Cross-lingual Parsing with Polyglot Training and Multi-treebank Learning: A Faroese Case Study

1 code implementation WS 2019 James Barry, Joachim Wagner, Jennifer Foster

Finally, we apply multi-treebank modelling to the projected treebanks, in addition to or alternatively to polyglot modelling on the source side.

APE through Neural and Statistical MT with Augmented Data. ADAPT/DCU Submission to the WMT 2019 APE Shared Task

no code implementations WS 2019 Dimitar Shterionov, Joachim Wagner, F{\'e}lix do Carmo

Automatic post-editing (APE) can be reduced to a machine translation (MT) task, where the source is the output of a specific MT system and the target is its post-edited variant.
