Abstract:

Despite the tremendous improvements achieved in less than a decade by neural models, NLP is still far from reaching language equality (i.e. comparable performance in all languages). The uneven amount of data available in different languages is often recognized as the main culprit. In this talk I will discuss recent work that acknowledges this situation and attempts to address it, not by collecting or synthesizing more data, but by exploiting linguistic information already existing for a large number of high- to very-low-resourced languages. In particular I will show how typological features can be used to learn language embeddings that boost the quality of a multilingual dependency parser. In the second part of the talk, I will discuss another obstacle to language inequality, namely the fact that some languages are intrinsically more difficult to model than others, even when controlling for training data size. Specifically, I will present recent results on the effect of word order freedom and case marking on the quality of state-of-the-art neural machine translation.

Bio:

Arianna Bisazza is Assistant Professor in Computational Linguistics at the University of Groningen, The Netherlands. Her research aims to identify the intrinsic limitations of current language modeling paradigms, and to improve the quality of machine translation for challenging language pairs. She previously worked as a postdoc at the University of Amsterdam and as a research assistant at Fondazione Bruno Kessler, Trento.
