AI总结:

本文针对德语行政法律规范文本,比较基于规则系统、深度判别模型和深度生成模型三种NER方法,发现深度判别模型最适合处理十类语义与句法异质实体。

摘要:

我们将NER应用于德语文本的一个特定法律文本子体裁:即规范公共服务行政中行政流程的法律规范体裁。对此类文本的分析涉及识别文本片段,这些片段实例化了由公共服务行政专业人员确定的十个类别之一。我们研究并比较了用于执行命名实体识别(NER)以检测这些类别的三种方法:基于规则的系统、深度判别模型和深度生成模型。我们的结果表明,深度判别模型的表现优于基于规则的系统以及深度生成模型;后两者的表现大致相当,并在不同类别上互有胜负。这一有些令人惊讶的结果的主要原因可以说是,分析中使用的类别在语义和句法上具有异质性,这与更标准的NER任务中使用的类别形成对比。与通用LLM以及设计基于规则的NER系统的人类语言学家相比,深度判别模型似乎更有能力处理这种异质性。

英文摘要:

We apply NER to a particular sub-genre of legal texts in German: the genre of legal norms regulating administrative processes in public service administration. The analysis of such texts involves identifying stretches of text that instantiate one of ten classes identified by public service administration professionals. We investigate and compare three methods for performing Named Entity Recognition (NER) to detect these classes: a Rule-based system, deep discriminative models, and a deep generative model. Our results show that Deep Discriminative models outperform both the Rule-based system as well as the Deep Generative model, the latter two roughly performing equally well, outperforming each other in different classes. The main cause for this somewhat surprising result is arguably the fact that the classes used in the analysis are semantically and syntactically heterogeneous, in contrast to the classes used in more standard NER tasks. Deep Discriminative models appear to be better equipped for dealing with this heterogenerity than both generic LLMs and human linguists designing rule-based NER systems.
