Riksdagsdebatter.se – An Interface to Explore Swedish Parliamentary Debates Since 1867

This paper introduces version 1.0 of riksdagsdebatter.se, a freely available and user-friendly interface for searching, filtering, and exploring Swedish parliamentary speeches since 1867. The underlying corpus is based on open-access data from the Swedish Parliament, further processed and enriched within the SWERIK project, including re-OCRing the debate records, segmenting the text into individual speeches, and adding structured metadata, with ongoing improvements to data quality. The corpus currently comprises over one million annotated speeches, totaling approximately 450 million words, and offers a comprehensive record of political debate in modern Swedish history. This resource has wide-ranging applications for researchers and students in digital humanities, history, political science, and sociology, as well as for journalists, policymakers, and the general public. Version 1.0 of riksdagsdebatter.se provides four primary tools: word trends, keyword in context, n-gram analysis, and the ability to create and download filtered sub-corpora.
