摘要:

词汇语义变化检测是一个新兴的研究领域。包括预处理和后处理在内的模型的最佳微调在很大程度上尚不清楚。我们通过以下方式优化现有模型:(i)对大型语料库进行预训练,并对历时目标语料库进行改进,以解决臭名昭著的小数据问题;(ii)应用已被证明可以提高同步任务性能的后处理转换。我们的研究结果提供了一个指导的应用和优化的词汇语义变化检测模型在各种学习场景。

英文摘要:

Lexical semantic change detection is a new and innovative research field. The optimal fine-tuning of models including pre- and post-processing is largely unclear. We optimize existing models by (i) pre-training on large corpora and refining on diachronic target corpora tackling the notorious small data problem, and (ii) applying post-processing transformations that have been shown to improve performance on synchronic tasks. Our results provide a guide for the application and optimization of lexical semantic change detection models across various learning scenarios.
