摘要:

可靠的自动可读性评估方法有可能影响从机器翻译到自学的各个领域。最近,德语的大语言模型(如GBERT和GPT-2-Wechsel)已经可用,允许开发基于深度学习的方法,这些方法有望进一步改进自动可读性评估。在这篇文章中,我们研究了微调GBERT和GPT-2-Wechsel模型的集合可靠地预测德语句子可读性的能力。我们将这些模型与语言特征相结合,并研究了预测性能对集合大小和组成的依赖性。GBERT和GPT-2-Wechsel的混合系综比仅由GBERT或GPT-2-Wechsel模型组成的相同大小的系综表现更好。我们的模型在GermEval 2022共享任务中对德语句子的文本复杂性评估进行了评估。在样本外数据上,我们的最佳集成实现了0.435的均方根误差。

英文摘要:

Reliable methods for automatic readability assessment have the potential to impact a variety of fields, ranging from machine translation to self-informed learning. Recently, large language models for the German language (such as GBERT and GPT-2-Wechsel) have become available, allowing to develop Deep Learning based approaches that promise to further improve automatic readability assessment. In this contribution, we studied the ability of ensembles of fine-tuned GBERT and GPT-2-Wechsel models to reliably predict the readability of German sentences. We combined these models with linguistic features and investigated the dependence of prediction performance on ensemble size and composition. Mixed ensembles of GBERT and GPT-2-Wechsel performed better than ensembles of the same size consisting of only GBERT or GPT-2-Wechsel models. Our models were evaluated in the GermEval 2022 Shared Task on Text Complexity Assessment on data of German sentences. On out-of-sample data, our best ensemble achieved a root mean squared error of 0.435.
