Andres Karjus, CLE, University of Edinburgh<\/em><\/p>\n Tuesday, 31.03.2020 Language change can be driven by a number of things, including social factors, evolutionary learning and communication biases, top-down language planning, or just random drift. In this talk, I will discuss the role of changing communicative needs in lexical change. The corpus-based component focuses on lexical competition and colexification. Here, competition refers to a situation where two or more words compete to be used in the same meaning space. Colexification refers to a word being used to refer to two or more meanings that are or could be otherwise expressed by individual words. I demonstrate how both processes, as well as changes in communicative need, can be detected and measured in diachronic corpora, using language-agnostic, unsupervised lexicostatistical approaches supported by word embeddings. Finally, I will discuss a work in progress artificial language experiment designed to investigate the effects of sense similarity and communicative need on colexification preferences.<\/p>\n slides<\/a>\u00a0|\u00a0recording<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Changing communicative needs and the structure of the lexicon: corpus-based and experimental approaches Andres Karjus, CLE, University of Edinburgh Tuesday, 31.03.2020 11:00 – 11:40 Room: [virtual Zoom talk] Language change can be driven by a number of things, including social factors, evolutionary learning and communication biases, top-down language planning, or just random drift.
