Abstract: This tutorial provides an overview of current approaches, problems and challenges in the detection of lexical semantic change. At its core, computational modelling of semantic change consists of the following: (1) Modelling word meaning, typically using unsupervised methods applied to diachronic corpora; (2) modelling meaning change, based on the results of the above; (3) evaluation. The tutorial will provide an introduction to lexical semantic change and an overview of the resources available (corpora, pre-trained diachronic models and data sets). We will highlight issues related to the creation and use of diachronic corpora and different procedures for annotating data. We will then present the current state of the art in automatic detection of LSC, provide a hands-on section on available systems and tools, and open the floor for discussion on possible applications.
