[AI-Generated Summary]: The CASCADE (Computational Analysis of Semantic Change Across Different Environments) network held its third doctoral training and research camp at the University of Helsinki from August 20-22, 2025. The network, funded by Horizon Europe under the Marie Skłodowska-Curie Actions Doctoral Networks, brings together 10 PhD students and supervisors from University College Cork, University of Sheffield, University of Helsinki, KU Leuven, and Universität des Saarlandes. The training focused on understanding the interplay between data, questions and methods in computational text analysis, with sessions on language models for textual analysis, semantic drift and intellectual history, and different computational approaches to text analysis. CASCADE addresses skills deficits in retrieving, critically evaluating and using large volumes of textual data in academic, public and commercial sectors.
