Big Data and the gendering of Parliamentary language

Luke Blaxill discusses the ways in which Big Data techniques can
introduce quantification into long-standing historical debates.
His example is the case of female MPs in the House of Commons.
How is the language they use different to that of male MPs and do
they represent "women's issues" more effectively than men?
Blaxill uses text mining techniques to investigate the feminist
claim that women's contributions in the Commons are substantively
different to men's and whether any "gender effect" is
strengthening or weakening with the rise in female numbers,
especially since 1997.
