Abstract

This paper contributes to ongoing scholarly debates on the merits and limitations of computational legal text analysis by reflecting on the results of a research project documenting exceptional COVID-19 management measures in Europe. The variety of exceptional measures adopted in countries characterized by different legal systems and natural languages, as well as the rapid evolution of such measures, pose considerable challenges to manual textual analysis methods traditionally used in the social sciences. To address these challenges, we develop a supervised classifier to support the manual coding of exceptional policies by a multinational team of human coders. After presenting the results of various natural language processing (NLP) experiments, we show that human-in-the-loop approaches to computational text analysis outperform unsupervised approaches in accurately extracting policy events from legal texts. We draw lessons from our experience to ensure the successful integration of NLP methods into social science research agendas.

从多语言法律文本中提取和分类特殊的COVID-19措施:自动化方法的优点和局限性
本文通过反思一个记录欧洲特殊COVID-19管理措施的研究项目的结果,为正在进行的关于计算法律文本分析的优点和局限性的学术辩论做出贡献。以不同法律制度和自然语言为特征的国家所采取的各种特殊措施,以及这些措施的迅速演变,对传统上用于社会科学的手工文本分析方法构成了相当大的挑战。为了应对这些挑战,我们开发了一个有监督的分类器,以支持由人类编码员组成的跨国团队对异常策略进行手动编码。在展示了各种自然语言处理(NLP)实验的结果之后,我们表明,在从法律文本中准确提取政策事件方面,人类在循环中的计算文本分析方法优于无监督方法。我们从我们的经验中吸取教训,以确保将NLP方法成功地整合到社会科学研究议程中。

期刊介绍: Regulation & Governance serves as the leading platform for the study of regulation and governance by political scientists, lawyers, sociologists, historians, criminologists, psychologists, anthropologists, economists and others. Research on regulation and governance, once fragmented across various disciplines and subject areas, has emerged at the cutting edge of paradigmatic change in the social sciences. Through the peer-reviewed journal Regulation & Governance, we seek to advance discussions between various disciplines about regulation and governance, promote the development of new theoretical and empirical understanding, and serve the growing needs of practitioners for a useful academic reference.
