Modeling Word Formation in English--German Neural Machine Translation

no code implementations ACL 2020 Marion Weller-Di Marco, Alex Fraser, er

This paper studies strategies to model word formation in NMT using rich linguistic information, namely a word segmentation approach that goes beyond splitting into substrings by considering fusional morphology.

Cross-lingual Annotation Projection Is Effective for Neural Part-of-Speech Tagging

no code implementations WS 2019 Matthias Huck, Diana Dutka, Alex Fraser, er

We tackle the important task of part-of-speech tagging using a neural model in the zero-resource scenario, where we have no access to gold-standard POS training data.

Coreference and Coherence in Neural Machine Translation: A Study Using Oracle Experiments

no code implementations WS 2018 Dario Stojanovski, Alex Fraser, er

We show that NMT models taking advantage of context oracle signals can achieve considerable gains in BLEU, of up to 7. 02 BLEU for coreference and 1. 89 BLEU for coherence on subtitles translation.

Two Methods for Domain Adaptation of Bilingual Tasks: Delightfully Simple and Broadly Applicable

1 code implementation ACL 2018 Viktor Hangya, Fabienne Braune, Alex Fraser, er, Hinrich Sch{\"u}tze

Bilingual tasks, such as bilingual lexicon induction and cross-lingual classification, are crucial for overcoming data sparsity in the target language.

Addressing Problems across Linguistic Levels in SMT: Combining Approaches to Model Morphology, Syntax and Lexical Choice

no code implementations EACL 2017 Marion Weller-Di Marco, Alex Fraser, er, Sabine Schulte im Walde

Many errors in phrase-based SMT can be attributed to problems on three linguistic levels: morphological complexity in the target language, structural differences and lexical choice.
