Datasets present text data stemming from academic articles (Scopus and WoS) and Policy documents collected from EU institutional repositories (European Commission, European Parliament, Council of the European Union). The data was collected from January to May 2023, as part of the "Digital Sovereignty by Design" research project framework. The primary purpose of this data collection is to conduct topic modelling, namely Latent Dirichlet Allocation (LDA), in order to identify current debates on digital sovereignty through international relations and political science lenses. We seek to identify and demonstrate the state-of-the-art with revealing trends and insights, mapping complex research and the political landscape of digital sovereignty issues in the EU. The objectives are (1) to identify the role played by the concept of digital sovereignty in different fields of studies; (2) to highlight recent trends in the study of digital sovereignty; (3) to identify, within those trends, the most common topics related to digital sovereignty and to trace their development over time; and (4) to explore how those trends and topics related to political regulation and governance within the digital sovereignty sphere. We present five datasets. One dataset contained academic articles data on digital sovereignty, and four other datasets collected policy documents from EU institutions. The academic articles' datasets contain complete bibliographic information, abstract and keywords (if available) from 2013 to 2023 with a total N of 156 texts. The datasets for the policy documents include the document's title and its complete text: European Commission from 2009 to 2023 with a total N of 2019 texts (61 from Register; 158 from Commonly used documents); European Parliament from 2011 to 2023 with total N of 368 texts; and Council of the European Union from 2001 to 2023 with total N of 221 texts.The ‘Digital Sovereignty by Design’ project will 1) engage with current law and policy approaches to cybersecurity in the United Kingdom and in the European Union, 2) identify how the EU’s current shift towards a digital sovereignty approach may negatively impact upon UK private-sector technology providers, in particular microprocessors, and 3) consider ways in which these negative impacts may be mitigated. Thus, this project addresses how interaction and competition between stakeholders influence the establishment of regulatory regimes over new technological innovations, or categories of technology, related to digital security and data privacy.

We collected data from two distinct types of sources: (1) Text data stemming from academic articles (digital sovereignty); (2) Text data stemming from policy documents produced by three of the main EU institutions. The main purpose of this data collection is to cover all discussions regarding the digital sovereignty concept within the academic and policy fields. Academic Articles: One dataset was created concerned with the concept of digital sovereignty. The collected articles mainly stem from International Relations, European Union Studies, Science and Technology Studies, and Law. The collection was carried out taking into account the following criteria: we collected only peer-reviewed articles; the collection was limited to English language articles; the time period was not set and was determined by the available articles: for Web of Science (WoS) from 2014 to 2023 and Scopus from 2013 to 2023; the search was based on the keyword "digital sovereignty". The collection of policy documents texts-data was carried out from open databases (repositories) of the three main EU institutions: the European Commission, the European Parliament, and the Council of the European Union. For uniformity of data collection, uniform selection criteria were applied: keywords: "digital sovereignty", "data sovereignty", "technology sovereignty", "cyber sovereignty"; the collection was limited to English language documents; the collection included all types of documents (except tables, Amendments and graphs); the time period was not set; in the case of large documents and reports, the abstract, the introduction, the executive summary, or the conclusion were collected.
