Chapter 6. Establishing a ‘new normal’
-
Matt Gee
Abstract
In this chapter we introduce statistical methods and associated visualisations for the analysis of lexical change on a monthly basis in a 1.8-billion word news corpus spanning over 30 years. In previous work (Kehoe et al. 2022) we found examples of word frequency change in a data-driven manner by applying existing statistical tests. An ongoing limitation is that, as our diachronic corpus grows, so too does the possibility of a word exhibiting multiple frequency changes in different directions. This chapter reframes the problem as one of time-series segmentation, dividing the frequency history of a word into timespans exhibiting consistent upward or downward change. We then determine reasons for such changes by applying horizon graph visualisations to collocates.
