Dimensions of Semantic Change: Applying the SIBling Framework to Mental Health Concepts Dimensions of Semantic Change: Applying the SIBling Framework to Mental Health Concepts Invited by: Dr. Pablo Mosteiro Romero: https://www.uu.nl/staff/PJMosteiroRomero Location: Natural Language and Text Processing Lab, University of Utrecht: https://nlp.sites.uu.nl/ Promotion: https://nlp.sites.uu.nl/2025/09/11/nltp-content-meetings-september-16-dimensions-of-semantic-change-applying-the-sibling-framework-to-mental-health-concepts-by-naomi-baes/ Title: Dimensions of Semantic Change: Applying the SIBling Framework to Mental Health Concepts Abstract: Lexical semantic change takes many forms, yet existing approaches often examine them in isolation. I present SIBling, a three-dimensional framework for modelling semantic change through shifts in (1) Sentiment (the valence of a word’s contexts), (2) Intensity (emotional arousal or the use of intensifiers), and (3) Breadth (the diversity of contexts in which a word appears). Together, these dimensions provide an integrated and computationally efficient way of mapping how the meanings of concepts evolve over time. I illustrate the framework with case studies of mental health related concepts, showing how they have broadened, intensified, or shifted in sentiment across decades of text. These results illuminate cultural trends such as pathologization, stigma, and concept creep, demonstrating how the SIBling toolkit captures capture socially significant conceptual change.
