Several papers accepted at EMNLP 2018

NLP Research

The NLP research group in the Machine Learning section at DIKU has just had several papers accepted to one of the top conferences in the field, EMNLP, in addition to the prestigious co-located conference CoNLL and the workshops BlackBoxNLP and WASSA.

Empirical Methods in Natural Language Processing (EMNLP) is a leading conference in the area of Natural Language Processing. This year the NLP group at DIKU has a total of 16 papers accepted at the conference (7 at EMNLP, 4 at CoNLL, 4 at BlackBoxNLP and 1 at WASSA). The research themes across the accepted papers are centred around multitask learning, multilingual learning, and question answering.

For example, PhD Yova Kementchedjhieva and Professor Anders Søgaard together with Sebastian Ruder, PhD at National University of Ireland, and Ryan Cotterell, PhD at Johns Hopkins University, submitted a paper on Generalizing Procrustes Analysis for Better Bilingual Dictionary Induction, which proposes a different take on machine translation. Currently machine translation relies on the availability of parallel data in different languages - think the Rosetta Stone, where the knowledge on a well-known language is used to decode an unknown language. For many smaller languages, this kind of data is scarce or non-existent, which motivates work towards machine translation based on non-parallel monolingual data. The paper introduces an advancement in this field, whereby using Generalized Procrustes Analysis we can achieve state-of-the-art results on the task of Bilingual Dictionary Induction, core to machine translation from non-parallel data.
