摘要:

受计算机视觉上的归纳迁移学习的启发,已经做出了许多努力来训练情境化的语言模型,以提高自然语言处理任务的性能。这些模型大多是在大型通用领域语料库(如新闻、书籍或维基百科)上训练的。尽管这些预先训练的通用语言模型很好地感知了语言结构的语义和句法本质,但在现实世界的特定领域场景中利用它们仍然需要考虑一些实际因素,如标记分布偏移、推理时间、内存、以及他们在多个任务中的同时熟练程度。在本文中,我们专注于法律领域,并提出如何不同的语言模型紧张的一般领域语料库可以最好地定制多个法律文件审查任务。我们比较他们的效率方面的任务性能和目前的实际考虑。

英文摘要:

Inspired by the inductive transfer learning on computer vision, many efforts have been made to train contextualized language models that boost the performance of natural language processing tasks. These models are mostly trained on large general-domain corpora such as news, books, or Wikipedia.Although these pre-trained generic language models well perceive the semantic and syntactic essence of a language structure, exploiting them in a real-world domain-specific scenario still needs some practical considerations to be taken into account such as token distribution shifts, inference time, memory, and their simultaneous proficiency in multiple tasks. In this paper, we focus on the legal domain and present how different language model strained on general-domain corpora can be best customized for multiple legal document reviewing tasks. We compare their efficiencies with respect to task performances and present practical considerations.
