A new approach for detecting changes in word meaning over time

Words change their meanings over time, but tracking these changes has traditionally required painstaking manual analysis by linguists. In recent years, researchers have been using computational models to automatically detect when semantic change happens, and how much of a change has occurred. Recent research led by Associate Professor Nina Tahmasebi and her colleagues in the Change is Key! program introduces innovative computational methods for detecting qualitative features of semantic change, opening new possibilities for understanding language evolution at scale.
