An interactive visualization of Google Books Ngrams with R and Shiny

Authors: Schlüter, Julia and Vetter, Fabian

Using the re-emergence of the /h/ onset from Early Modern to Present-Day English as a case study, we illustrate the making and the functions of a purpose-built web application named (an:a) lyzer for the interactive visualization of the raw n-gram data provided by Google Books Ngrams (GBN). The database has been compiled from the full text of over 4.5 million books in English, totalling over 468 billion words and covering roughly five centuries. We focus on bigrams consisting of words beginning with graphic <h> preceded by the indefinite article allomorphs a and an, which serve as a diagnostic of the consonantal strength of the initial /h/. The sheer size of this database affords us the possibility to attain a maximal diachronic resolution, to distinguish highly specific groups of <h>-initial lexical items, and even to trace the diffusion of the observed changes across individual lexical units. The functions programmed into the app enable us to explore the data interactively by filtering, selecting and viewing them according to various parameters that were manually annotated into the data frame. We also discuss limitations of the database, of the app and of the explorative data analysis. The app is publicly accessible online at https://osf.io/ht8se/.
