A Moral Foundations Dictionary for the European Portuguese Language: The Case of Portuguese Parliamentary Debates

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Moral Foundations Theory (MFT) has shown that American
liberals and conservatives rely on fundamentally different moral principles, offering a different perspective on the deepening political divide in US politics. However, results outside the US have been less clear, particularly in countries with a more diverse political landscape that does not fall into the traditional Liberal/Conservative dichotomy. Here, we expand the Moral
Foundations Dictionary to European Portuguese, which we then use to analyze 10 years of transcripts of parliamentary sessions using standard Data Science and Text Mining techniques. Despite a larger number of represented parties, we show that no traditional parties fall into the Conservative or Liberal characterization and that the political landscape in Portugal is relatively homogeneous with the major difference observed concerning the dichotomy between Government and the parliament.
