Insight Dáil Éireann Ngram Viewer — 2006 to 2015
Inspired by the Google Books Ngram Viewer, we parsed a collection of 498,161 English language speeches made in Dáil Éireann from January 2006 to December 2015, in order to get a high level picture of the language and issues being discussed by TDs during that time. In this context an ngram refers to a word or phrase used by a TD in a Dáil speech.
Having collected speeches from KildareStreet.com, we extracted all words and phrases, up to three words long, from the text of the speeches. After removing infrequent words/phrases and non-informative "stopwords", we created an index of frequencies for 15,364,891 unique words and phrases. Based on this index, the graph below can be used to visualise how the discussion in the Dáil has evolved over the last decade. The y-axis shows the percentage of speeches from each month that contain the specified words/phrases. More detail on the methodology involved are provided in this blog post.
