Nina Tahmasebi leads a large research program by RJ, Change is Key! that started in 2022 and spans six years. Within this program,
state-of-the-art computational methods to detect different aspects of semantic change and variation are developed, to facilitate and simplify research in the text-based humanities and social sciences, historical linguistics and lexicography. The program has two main aims, firstly to develop corpus-based methods for detecting semantic change (over time) and variation (across social groups and media types). Within the program, researchers from NLP collaborate with researchers from social sciences, gender studies, and literature to answer their research questions and to develop methods and research methodology for their specific needs. By identifying and handling changes in language automatically, a correct interpretation of our language is ensured and studies of our contemporary and historical societies are facilitated. There are about 15 participating researchers and one research engineer from six participating universities, IMS Stuttgart, Queen Mary University of London, University of Lund, Institute for Analytical Sociology (IAS) Linköping University, KU Leuven.
Nina also leads the project Towards Automatic Detection of Language Change (2019 - 2022) with Simon Hengchen, Dominik Schlechtweg, and Maria Koptjevskaja Tamm which has been running since 2019. Within the project, the first ever international workshop on computational methods for historical language change (LChange'19) and two follow-ups have been organized, several talks and given a few local workshops have been given in international venues including at the Alan Turing Institute. A large survey paper on Computational Approaches to Lexical Semantic Change has been published. Within the project, a large effort on evaluation has been made SemEval-2020: Task 1 on Unsupservised Lexical Semantic Change Detection.
Since 2023, Nina Tahmasebi is at the department of Philosophy, Linguistics and Theory of Science, FLoV at the University of Gothenburg.
