SUMMARY:Gaël LE MENS (Universitat Pompeu Fabra) - Scaling Political Texts with ChatGPT
DESCRIPTION:Sociology seminar – Thursdays\nTime: 12:00 pm – 1:30 pm \nDate: 16th May 2024\nPlace: room 3105 \nZOOM LINK: https://zoom.us/j/97751150432?pwd=NUpGdDg1OW9uSFNxZWNxUTR0ZjRNUT09 \n\nGaël LE MENS (Universitat Pompeu Fabra) – Scaling Political Texts with ChatGPT\n  \nAbstract: \nWe use GPT-4 to obtain position estimates of political texts in continuous spaces. We develop and validate a new approach by positioning British party manifestos on the economic\, social\, and immigration policy dimensions and tweets by members of the US Congress on the left-right ideological spectrum. For the party manifestos\, the correlation between the positions produced by GPT-4 and experts is 93% or higher\, a performance similar to or better than that obtained with crowdsourced position estimates. For individual tweets\, the positions obtained with GPT-4 achieve a correlation of 91% with crowdsourced position estimates. For senators of the 117th US Congress\, the positions obtained with GPT-4 achieve a correlation of 97% with estimates based on roll call votes and of 96% with those based on campaign funding. Correlations are also substantial within party\, indicating that position estimates produced with GPT-4 capture within-party differences between senators. Overall\, using GPT-4 for ideological scaling is fast\, cost-efficient\, and reliable. This approach provides a viable alternative to scaling by both expert raters and crowdsourcing. \n  \nOrganizers: Annina Cleasson\, Paola Tubaro\, Patrick Präg (CREST Sociology unit) \n  \nSponsors: CREST \n  \n
