One-Shot Neural Cross-Lingual Transfer for Paradigm Completion
Katharina Kann, Ryan Cotterell, Hinrich Schütze · 2017
We present a novel cross-lingual transfer method for paradigm completion, the task of mapping a lemma to its inflected forms, using a neural encoder-decoder model, the state of the art for the monolingual task.We use labeled data from a high-resource language to increase performance on a lowresource language.In experiments on 21 language pairs from four different language families, we obtain up to 58% higher accuracy than without transfer and show that even zero-shot and one-shot learning are possible.We further find that the degree of language relatedness strongly influences the ability to transfer morphological knowledge.
