摘要:

在过去的几年里,为非母语学习者开发语言能力模型一直是NLP研究的一个活跃领域。尽管语言能力本质上是多维的,但现有研究在构建模型时通常会考虑单一的“总体能力”。此外,现有的方法也一次只考虑一种语言。本文描述了我们对预训练和微调的多语言嵌入在执行多维多语言语言能力分类中的作用的实验和观察。我们报告的实验与三种语言-德语,意大利语和捷克语-和模型的七个方面的熟练程度,从词汇控制到社会语言学的适当性。我们的研究结果表明,虽然微调嵌入是有用的多语言能力建模,没有一个功能实现一致的最佳性能的语言能力的所有方面。所有代码、数据和相关补充材料可在https://github.com/nishkalavallabhi/MultidimCEFRScoring上找到。

英文摘要:

Development of language proficiency models for non-native learners has been an active area of interest in NLP research for the past few years. Although language proficiency is multidimensional in nature, existing research typically considers a single "overall proficiency" while building models. Further, existing approaches also considers only one language at a time. This paper describes our experiments and observations about the role of pre-trained and fine-tuned multilingual embeddings in performing multi-dimensional, multilingual language proficiency classification. We report experiments with three languages -- German, Italian, and Czech -- and model seven dimensions of proficiency ranging from vocabulary control to sociolinguistic appropriateness. Our results indicate that while fine-tuned embeddings are useful for multilingual proficiency modeling, none of the features achieve consistently best performance for all dimensions of language proficiency.
