D4Science is a digital infrastructure designed to offer diverse communities of practices a comprehensive suite of services through tailored and co-created virtual research environments promoting collaboration and innovation. It is operated as a not-for-profit service. Its development was supported by several EU-funded projects.

D4Science-enabled virtual research environments support the entire research lifecycle—from data management and analysis to publication and collaboration. By integrating services, tools, and resources, D4Science advances open science practices.

Mission: Shift scholarly communication towards openness and transparency and facilitate innovative ways to communicate and monitor research. We foster the open science dialogue for policies and their implementation in Europe and beyond. Our network of 34 National Open Access Desks (NOADs) operates a European Helpdesk supporting a coordinated transition to Open Science. We provide interoperability services that connect research and enable researchers, content providers, funders and research administrators to easily adopt Open Science.

The SoBigData e-infrastructure offers access to over 205 resources (social datasets, Big Data analysis algorithms and courseware) designed to support data scientists in the execution of large scale experiments. The SoBigData e-infrastructure is currently used by a vast and diverse pool of stakeholders, including 120 companies and over 4,700 registered users, with daily peaks of accesses and executions in the millions.

The SoBigData e-infrastructure offers access to six domains:

• Societal debates and online misinformation studies how the information is created and how it evolves and influences debates;
• Sustainable cities for citizens focuses on all-encompassing urban challenges, aiming at value creation for city stakeholders: population, infrastructure, environment, and policies, and provide applications for any type of service for the smart city ecosystem;
• Demography, economics and finance 2.0 measures the patterns of well-being and poverty at local and global scale, empowering governments and policy makers with the unprecedented opportunity to nowcast relevant economic quantities and compare different countries, regions and cities;
• Migration Studies analyses the developing of novel methods for studying migration phenomenon, also keeping an eye on the protection of vulnerable groups;
• Sport data science combines data with analytical tools in order to unveil the complexity underlying sports and address many challenging tasks;
• Trustworthy Artificial Intelligence and Impact on Society provides a forum for studying impacts of artificial intelligence on the future of society.
