Programming for Corpus Linguistics with Python and Dataframes

This Element offers intermediate or experienced programmers algorithms for Corpus Linguistic (CL) programming in the Python language using dataframes that provide a fast efficient intuitive set of methods for working with large complex datasets such as corpora. This Element demonstrates principles of dataframe programming applied to CL analyses as well as complete algorithms for creating concordances; producing lists of collocates keywords and lexical bundles; and performing key feature analysis. An additional algorithm for creating dataframe corpora is presented including methods for tokenizing part-of-speech tagging and lemmatizing using spaCy. This Element provides a set of core skills that can be applied to a range of CL research questions as well as to original analyses not possible with existing corpus software.
