This paper presents the design of one of Sweden’s largest dig- ital humanities projects, SweTerror, that through an interdisciplinary multi- modal methodological approach develops an extensive speech-to-text digital HSS resource. SweTerror makes a major contribution to the study of terrorism in Swe- den through a comprehensive mixed methods study of the political discourse on terrorism since the late 1960s. Drawing on artificial intelligence in the form of state-of-the-art language and speech technology, it systematically analyses all forms of relevant parliamentary utterances. It explores and curates an exhaus- tive but understudied multi-modal collection of primary sources of central rele- vance to Swedish democracy: the audio recordings of the Swedish Parliament’s debates. The project studies the framing of terrorism both as policy discourse and enacted politics, examining semantic and emotive components of the parliamen- tary discourse on terrorism as well as major actors and social networks involved. It covers political responses to a range of terrorism-related issues as well as fac- tors influencing policy-makers’ engagement, including political affiliations and gender. SweTerror also develops an online research portal, featuring the com- plete research material and searchable audio made readily accessible for further exploration. Long-term, the project establishes a model for combining extraction © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022 K.
