The data originate from the 1970s and are stored in archives from the UK and US governments, plus the United Nations High Commissioner for Refugees (UNHCR). The overarching theme is to analyse the involvement of the UK, the USA, and the UNHCR in different refugee cases that occurred during the 1970s. To do so, we (1) identify the main topics in each document; (2) investigate the transmission of topics horizontally (between organizations) and vertically (through time); and (3) suggest targeted areas of the document set for further close reading by historians. Standard Optical Character Recognition and object detection are used to extract information from documents and categorize them. Then, natural language processing (NLP) methods like topic modelling and clustering are used to identify topics and the relationships between them across time. The results identify several main themes covered by different organizations and how the focus of each organization changes diachronically. Besides its academic contribution, this study also demonstrates how, through the use of existing techniques with limited customization, digital technologies in the hands of the historian can augment and complement qualitative methods in bringing to light the themes and trends demonstrated in large bodies of historical documents.<\/jats:p>","DOI":"10.1093\/llc\/fqab018","type":"journal-article","created":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T20:17:26Z","timestamp":1613420246000},"page":"886-904","source":"Crossref","is-referenced-by-count":7,"title":["Topic modelling on archive documents from the 1970s: global policies on refugees"],"prefix":"10.1093","volume":"36","author":[{"given":"Philip","family":"Grant","sequence":"first","affiliation":[{"name":"Independent Researcher, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ratan","family":"Sebastian","sequence":"additional","affiliation":[{"name":"University of Edinburgh, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Allassonni\u00e8re-Tang","sequence":"additional","affiliation":[{"name":"Lab Dynamics of Language UMR 5596, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Cosemans","sequence":"additional","affiliation":[{"name":"KU Leuven Research Unit of History, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,3,30]]},"reference":[{"key":"2021103118082968500_fqab018-B1","doi-asserted-by":"crossref","first-page":"537","DOI":"10.1007\/s11634-017-0280-3","article-title":"Cluster-based sparse topical coding for topic mining and document clustering","volume":", 2","author":"Ahmadi","year":"2018","journal-title":"Advances in Data Analysis and Classification"},{"key":"2021103118082968500_fqab018-B2","doi-asserted-by":"crossref","first-page":"74","DOI":"10.1017\/CBO9781107286207.006","volume-title":"Explaining the History of American Foreign Relations","author":"Allen","year":"2016"},{"key":"2021103118082968500_fqab018-B3","author":"Baierer","year":"2019"},{"key":"2021103118082968500_fqab018-B4","doi-asserted-by":"crossref","first-page":"4607","DOI":"10.1073\/pnas.1717729115","article-title":"Individuals, institutions, and innovation in the debates of the French Revolution","volume":"115","author":"Barron","year":"2018","journal-title":"Proceedings of the Nationall Academy of Sciences of the United States of America"},{"key":"2021103118082968500_fqab018-B5","doi-asserted-by":"crossref","first-page":"91","DOI":"10.25071\/1920-7336.30610","article-title":"From political instrument to protection tool?
