Analysing the impact of cultural diversity on corporate performance by feeding half-million Glassdoor reviews through a "Latent Dirichlet Allocation topic modeling" machine learning algorithm: "the “bag of words” approach... inductively infers categories... a statistical model that looks for words that tend to co-occur."
Step 1: feed 1 million sentences containing "culture" or its synonyms: Asking "What words occurred around these words?... provided a reliable model of different cultural categories".
These were then used to analyse the complete reviews to determine what people within each company "say about its culture... do employees agree or disagree on what a firm’s culture is?", and compared that with its return on assets.
