Query: Choosing Transfer Languages for Cross-Lingual Learning   Cross-lingual transfer, where a high-resource transfer language is used to
improve the accuracy of a low-resource task language, is now an invaluable tool
for improving performance of natural language processing (NLP) on low-resource
languages. However, given a particular task language, it is not clear which
language to transfer from, and the standard strategy is to select languages
based on ad hoc criteria, usually the intuition of the experimenter. Since a
large number of features contribute to the success of cross-lingual transfer
(including phylogenetic similarity, typological properties, lexical overlap, or
size of available data), even the most enlightened experimenter rarely
considers all these factors for the particular task at hand. In this paper, we
consider this task of automatically selecting optimal transfer languages as a
ranking problem, and build models that consider the aforementioned features to
perform this prediction. In experiments on representative NLP tasks, we
demonstrate that our model predicts good transfer languages much better than ad
hoc baselines considering single features in isolation, and glean insights on
what features are most informative for each different NLP tasks, which may
inform future ad hoc selection even without use of our method. Code, data, and
pre-trained models are available at https://github.com/neulab/langrank
