Deliverable D3.2 Case study reports on positive and negative externalities presents the case study reports on positive and negative externalities in the use of big data that we have undertaken in the BYTE project. The case studies correspond to the domains of crisis informatics, culture, energy, environment, healthcare, maritime transportation and smart cities. Following a formal designed methodology, we have gathered evidence from the case studies by means of semi-structured interviews, disciplinary focus groups and literature review. Overall, we have conducted 49 interviews with data experts from each case study discipline and we have counted with 6-12 external domain experts per focus group.
The crisis informatics case study is focused on the use of social media – especially Twitter data – to support humanitarian relief efforts during crisis situations.
The culture case study examines a pan-European public initiative that provides open access to digitised copies of cultural heritage works.
The energy case study analyses the impact of big data in exploration and production of oil & gas in the Norwegian Continental Shelf.
The environment case study is probably the most mature in terms of big data. Stakeholders take for granted the availability of data, especially from authoritative sources such as prominent earth and space observation portals, and there is a growing interest in crowd-sourced data.
The healthcare case study is conducted within a health institute at a medical university in the UK. This institute facilitates the discovery of new genes, the identification of disease and innovation in health care utilising genetic data.
The maritime transportation case study analyses the use of big data in the shipping industry that accounts more than 90% of global trade.
Finally, the smart cities case study examines the creation of value from potentially massive amounts of urban data that emerges through the digitalized interaction of a city’s users with the urban infrastructure of resources.
