A public dataset of speeches in the Hansard, stored as a tibble class in RDS files, for the R programming language, and also available in CSV format.1 The dataset provides information on every speech made in the House of Commons between the parliament returned from the 1979 general election and the dissolution of parliament for the 2017 general election, with information on the speaking MP, their party, gender, birthdate2, starting and finishing dates as an MP, and age at the time of the speech. The dataset also includes all speeches made from 1936 to the dissolution of parliament for the 1979 general election. The post-1979 election dataset is labelled hansard_senti_post_V21
and the pre-1979 election dataset is labelled hansard_senti_pre_V21
.

The hansard_senti_post_V21
dataset contains 2,234,059 speeches and 404,581,972 words. The hansard_senti_pre_V21
dataset contains 2,977,461 speeches and 413,044,716 words. It can be accessed through Zenodo, and is distributed under a Creative Commons 4.0 BY-SA licence. The latest version, V2.1, includes includes an additional sentiment library, resulting in six different lexical libraries (see below, all using the same methods of calculation. Several duplicate speeches were also identified and removed.

Added additional sentiment calculation method based on this paper by Rheault et al. (2016).
Sentiment Classification Methods
The speeches have been classified for sentiment using a total of four libraries from the R package lexicon
by Tyler Rinker, one from the syuzhet
package by Michael Jockers, and one by Ludovic Rheault, Kaspar Beelen, Christopher Cochrane and Graeme Hirst. All classification has used the method in Tyler Rinker’s sentimentr
package. The libraries are:
-
The AFINN library, labelled
afinn
. The AFINN library was accessed through Matthew Jockers’ssyuzhet
package. {% cite nielsen2011 –file hansard-data %}. -
A variant of the syuzhet library, included in the
lexicon
package, labelledjockers
. {% cite jockers2015 –file hansard-data %}. -
The NRC Word-Emotion Association Lexicon, labelled
nrc
. The NRC library was access through thelexicon
package. {% cite mohammad2013 –file hansard-data %}. -
The Sentiwords library, labelled
sentiwords
. The library was accessed through thelexicon
package. {% cite baccianella2010 –file hansard-data %}. -
The Opinion Mining, Sentiment Analysis and Opinion Spam Detection library, labelled
hu
. The library was access through thelexicon
package. {% cite hu2004 –file hansard-data %}. -
A modified version of the unnamed lexicon from {% cite rheault2016 –file hansard-data %}, labelled
rheault
. As the method insentimentr
does not use distinguish between the same word that can occupy multiple lexical categories,3 I used the average polarity score assigned to such words.4
Summary Statistics
I have produced summary statistics with the mean and standard deviation of sentiment scores, average speech length, and sentiment score means and standard deviations weighted by the length of the speech. These are available for each MP, and by party, party group, government or opposition status and gender. Download all five tables in one XLSX workbook.
Dataset Variables
The hansard_senti_post_V21
and hansard_senti_pre_V21
datasets have slightly different variables, as there is more information available for all post-1979 MPs, and that is included in hansard_senti_post_V21
.

Methodology
The parlparse project provides scraped xml files of Hansard debate going back to 1936, and assigns an ID to each speaker. However, I could not find where the IDs assigned are linked to other information, such as constituencies or parties, or the MNIS ID system used by parliament. Long-serving MPs may also have dozens of these IDs assigned to them, and they are not consistently linked together. There are also substantial numbers of speeches where there is no ID assigned a speaker, and they are classified as ‘unknown’. I created a table with every possible combination of name and ID, and matched the speakers in that table to their MNIS ID, using a mixture of exact string, approximate string and manual matching. The information in this table was then matched to the complete list of speech IDs. In the case of commonly used names (e.g. the two Labour MPs named John Smith who were both members of the house between 1989 and 1992) I manually identified which MP was actually speaking by locating adjacent Hansard records where their full name, constituency or ministerial title was used. In a handful of cases I had to use the content of their speech and any adjacent speeches to provide further clues to an MPs identity.

Sarah Olney (mnis_id 4591) does not have a birth date listed in the Members Names Information Service, and I have been unable to locate her date of birth elsewhere, only the year of birth. Her birthdate is, as a consequence, listed as 1977-01-01, this will be amended to the correct month and day if her biography is updated. ↩︎
