An Automated Text Analysis of Diplomatic Speeches

heatmap ed.png

What is it?

  • An online open corpus containing the more than 80 thousand speeches delivered at the United Nations Security Council (UNSC) between 1995 and 2020. The next update will comprise all speeches delivered from 1992 and 2022.

  • An interactive tool that allows users to navigate through the corpus texts and its metadata, visualize the frequency of meetings and topics, and the outcomes of selected analysis of the speeches, such as keywords, sentiment, and similarity between members. It is possible to apply filters for member, topic, and time span.

Why is it significant?

  • Previous research on the UNSC relies on case studies, usually focusing on specific members or conflicts. The dataset makes it possible to study the Council as a whole, covering all of its members and all debated conflicts. Also, it contains a comprehensive set of variables providing a deeper look into the characteristics of each meeting, including the content of all speeches, complementing the information provided by the UN website and its reports.

Who will benefit from it?

  • The UNSC and UN Secretariat will have at their disposal detailed information about the Council’s practice during the whole post-Cold War period.

  • Diplomats, researchers, and UN experts interested in monitoring the practice of the UNSC and the positions expressed by its members through their speeches.

What stage is it at?

  • The process of collecting speeches for the new version of the dataset is complete. We already performed sentiment analysis in the corpus and ran descriptive analysis to observe the frequency of meetings by a preliminary version of the topics variable. It’s necessary to standardize topics’ labels and build the online platform to present all of the analyses.
