Grandma Karl is 27 years old -- research agenda for pseudonymization of
  research data
Elena Volodina Simon Dobnik Therese Lindström Tiedemann Xuan-Son Vu
Accessibility of research data is critical for advances in many research
fields, but textual data often cannot be shared due to the personal and
sensitive information which it contains, e.g names or political opinions.
General Data Protection Regulation (GDPR) suggests pseudonymization as a
solution to secure open access to research data, but we need to learn more
about pseudonymization as an approach before adopting it for manipulation of
research data. This paper outlines a research agenda within pseudonymization,
namely need of studies into the effects of pseudonymization on unstructured
data in relation to e.g. readability and language assessment, as well as the
effectiveness of pseudonymization as a way of protecting writer identity, while
also exploring different ways of developing context-sensitive algorithms for
detection, labelling and replacement of personal information in unstructured
data. The recently granted project on pseudonymization Grandma Karl is 27 years
old addresses exactly those challenges.
