摘要:

本研究的目的是探讨现有跨语言词嵌入评价方法的局限性,解决内在和外在跨语言评价方法之间缺乏相关性的问题。为了证明这一假设,我们构建了英语-俄语数据集的外部和内部评估任务,并比较了5种不同的跨语言模型对他们的表现。结果表明,即使在不同的内在基准上,分数也彼此不相关。我们可以得出这样的结论,使用人类参考作为跨语言词嵌入的基础事实是不合适的,除非你不明白母语者在他们的认知中是如何处理语义的。

英文摘要:

The aim of this work is to explore the possible limitations of existing methods of cross-language word embeddings evaluation, addressing the lack of correlation between intrinsic and extrinsic cross-language evaluation methods. To prove this hypothesis, we construct English-Russian datasets for extrinsic and intrinsic evaluation tasks and compare performances of 5 different cross-language models on them. The results say that the scores even on different intrinsic benchmarks do not correlate to each other. We can conclude that the use of human references as ground truth for cross-language word embeddings is not proper unless one does not understand how do native speakers process semantics in their cognition.
