 Hi! In this unit we will discuss various theoretical approaches to the formalization of word meaning. These theories provide frameworks for describing the relationship between words and conceptual structures on the one hand and for formalizing the sense relations among lexical items on the other. In the virtual session we will look at several theories of word meaning, more or less formal ones such as semantic fields, componential analysis, meaning postulates, and more cognitively oriented approaches such as semantic networks or frame-based approaches. Use the question sheet with its hyperlinks and its video links for guidance. The mastery worksheet is a dynamic multiple-choice task with questions about theories of word meaning. It will be easy to do after the virtual session. And the practical, as usual, provides you with data, this time with data ready to be defined theoretically, that is in terms of meaning components, semantic networks and so on. Very useful to illustrate the various theoretical approaches.
