Quantifying polysemy in Cognitive Sociolinguistics
This chapter uses various statistical techniques to explore the extralinguistic grounding of individual conceptualisations of polysemous adjectives in English, such as awesome, gay, wicked. It considers the extent to which individual conceptualisations are non-random and can be related to the socio-demographic characteristics of the speaker. The experimental survey data collected from 72 speakers is analysed via hierarchical agglomerative clustering, decision tree analysis, and logistic regression analysis. The results reveal that not only individual adjectives, as indicated in Robinson (2010a), but whole groups of polysemous adjectives currently undergoing semantic change form usage patterns that can be explained by a very similar sociolinguistic distribution. This study demonstrates that employing a socio-cognitive perspective when researching polysemy is hugely advantageous.
