Python script for discourse analysis on specific text files (attached)

This is a script, written to analyse the language used by parliamentarians in specific debates, in the context of my doctoral research ('From the anger of the Normans and translators save us Lord!' Opinions on translation and legal translation policy in Belgium, 1830-1914). It calculates the (relative) frequency with which certain terms were used within a chosen distance of a reference to translation or translators.
