ODISSEI is a data infrastructure that brings together existing data from the social sciences and economics and combines them with new data from a wide range of sources such as wearable devices, social media or administrative records, and provides the computational infrastructure to conduct complex and ground-breaking analysis. It makes its data and infrastructure available to scientists from many different disciplines and the subsequent analysis is widely used by government departments and research institutes to help better understand societal challenges and how to address them. By linking and enriching data with contextual information, developing innovative analytic and presentation tools, and offering world class, secure and ethical data management facilities, ODISSEI enhances the position of the Dutch social sciences as global leaders. In this application, we are asking for €500,000 to ensure that ODISSEI continues to grow, attract new partners and investment, and stay at the cutting edge of innovations in the social sciences. The funds will be used to extend and develop the ODISSEI data platform, a unique facility that is a global first in the field. It is the first infrastructure in the world to combine scientific data collections, administrative records, contextual (time and environmental) data and high-performance computing facilities in one environment, opening up new possibilities for social scientists. Some of the funding will also be used to strengthen the coordination of ODISSEI as it continues to expand and moves towards a sustainable future that serves a diverse and policy orientated community.
