Post-doc position: Developing Diversity Metrics for Social Media
People are using information technologies like news aggregators and social media platforms to get and share information at an increasing rate. This has great potential; a more knowledgeable citizenry creates more stable democracies. However, filtering and ranking algorithms such as recommender systems can contribute to increased polarization. Understanding and finding solutions to complex (societal) issues on the other hand often requires us to view those issues from a variety of perspectives.
The research will entail outlining which features of diversity in news promotes epistemic ends (e.g., knowledge, understanding), and tools for measuring this diversity. The use case will be focused on discussions of news on Twitter and the news sources that people link to from Twitter on debated topics. The results of the research will be a toolkit for measuring diversity on a variety of dimensions (e.g., diversity in viewpoint, diversity in topics, and diversity in reasons for or against a given viewpoint).
