摘要:

最近的研究表明,相关语言的嵌入可以提高序列标记的性能,即使是单语模型。在这篇分析论文中,我们研究了是否可以根据语言距离预测最佳辅助语言,并表明最相关的语言并不总是最佳辅助语言。此外,我们还证明了基于注意力的元嵌入可以有效地结合来自不同语言的预训练嵌入进行序列标记,并为五种语言的词性标记设置了新的最先进的结果。

英文摘要:

Recent work showed that embeddings from related languages can improve the performance of sequence tagging, even for monolingual models. In this analysis paper, we investigate whether the best auxiliary language can be predicted based on language distances and show that the most related language is not always the best auxiliary language. Further, we show that attention-based meta-embeddings can effectively combine pre-trained embeddings from different languages for sequence tagging and set new state-of-the-art results for part-of-speech tagging in five languages.
