摘要:

由于预先训练的语言模型的成功,近年来已经发布了英语以外的语言版本。这一事实意味着需要资源来评估这些模型。在西班牙语的情况下,有几种方法来系统地评估模型的质量。在本文中,我们缩小差距,通过建立两个评估基准。受先前工作的启发(Conneau和Kiela,2018; Chen等人,2019年),我们介绍了西班牙语SentEval和西班牙语DiscoEval,旨在评估独立和话语感知句子表征的能力。我们的基准测试包括相当多的预先存在的和新构建的数据集,这些数据集解决了来自各个领域的不同任务。此外,我们评估和分析了最新的预训练西班牙语语言模型,以展示其能力和局限性。作为一个例子,我们发现,对于话语评估任务的情况下,mBERT,一个语言模型在多种语言上训练,通常提供了一个更丰富的潜在的代表性比模型只与西班牙语的文档训练。我们希望我们的贡献将激励一个更公平的,更可比的,和不那么繁琐的方式来评估未来的西班牙语语言模型。

英文摘要:

Due to the success of pre-trained language models, versions of languages other than English have been released in recent years. This fact implies the need for resources to evaluate these models. In the case of Spanish, there are few ways to systematically assess the models' quality. In this paper, we narrow the gap by building two evaluation benchmarks. Inspired by previous work (Conneau and Kiela, 2018; Chen et al., 2019), we introduce Spanish SentEval and Spanish DiscoEval, aiming to assess the capabilities of stand-alone and discourse-aware sentence representations, respectively. Our benchmarks include considerable pre-existing and newly constructed datasets that address different tasks from various domains. In addition, we evaluate and analyze the most recent pre-trained Spanish language models to exhibit their capabilities and limitations. As an example, we discover that for the case of discourse evaluation tasks, mBERT, a language model trained on multiple languages, usually provides a richer latent representation than models trained only with documents in Spanish. We hope our contribution will motivate a fairer, more comparable, and less cumbersome way to evaluate future Spanish language models.
