The goal of this data collection has been to create a unified and easily accessible database with all the published documents of El Congreso De Los Diputados in raw text format. It contains more than 111.000 documents, including the diary of sessions of the Spanish Congress, as well as that of the Spanish Senate. A dataset of these characteristics is created for researchers to analyze various aspects of Spanish politics and legislation. This includes studying the law-making process, comparing it to other countries, and evaluating the effectiveness of policies. The dataset also promotes transparency and allows for research using Natural Language Processing techniques.
