The global volume of data is growing and is evaluated using increasingly complex algorithms. What does that mean for each individual? Researchers are investigating this question in the interdisciplinary project ABIDA (Assessing Big Data). The participants include scientists from the fields of ethics, sociology, economics, law, and political science, as well as laypeople. Other facilities on campus are also incorporated, including the art academy, the technical college, and the business informatics department. The analyses make use of results from public congresses, citizens' conferences, and a survey. Thus opportunities and risks of Big Data are elucidated from various perspectives - something no algorithm can do.
