Its main value lies in the possibility to find semantic patterns that would be difficult to identify otherwise. Such patterns may for instance be helpful to categorise documents in large archives or to discover the underlying topical structure of big corpora without the need to read each individual document. Although potentially a very efficient distant reading technique, the output may sometimes be difficult to interpret.<\/p><p>In this seminar, Lorella Viola present a method that uses the close reading technique Discourse-Historical Approach (DHA \u2013 Reisigl &#038; Wodak 2001) to refine TM. This combined methodology, \u201cdiscourse-driven topic modelling\u201d (DDTM), aims to enable researchers to triangulate linguistic, social, and historical data in order to make the topics more interpretable and unlock the full potential of TM. To test the methodology, she investigates public discourses produced by Italian migrants in the United States using a corpus of digitised Italian ethnic newspapers published in the United States between 1898 and 1920 (ChroniclItaly \u2013 Viola 2018). The results proved DDTM to be effective in obtaining a relatively quick categorisation of the topics discussed in the immigrant press. Moreover, the changing distribution of topics over time revealed how the Italian immigrant community negotiated their sense of connectedness with both the host country and the homeland and how the changing experience of migration, identity construction, and assimilation was reflected over time in the accounts of the minorities themselves. At the same time, without jeopardising the analytical depth of the findings, the method proved its value of minimising the risk of biases when identifying the topics which stemmed from the data rather than from preconceived assumptions.<\/p><p>The seminar is organised by the <a href=\"https:\/\/dhh.uni.lu\/\" target=\"_blank\" title=\"\" rel=\"noopener\">Doctoral Training Unit \u201cDigital History
