Title: Open access to research data and automatic pseudonymization. Two years with Mormor
Karl project.
Abstract: This talk will be devoted to the challenges of working with data that contains
personal information. I will describe a set of experiments with automatic pseudonymization
that we have performed within Mormor Karl project<https://mormor-karl.github.io/>.
Among others, experiments with detection and labeling of personal categories using BERT
models (Szawerna et al. 2024, 2025), attempts att using LLMs to "fill in the
blanks" when substituting personal information with pseudonyms (yet unpublished) and
a study on whether pseudonyms can provoke biased automated classifications (Muñoz Sánchez
et al. 2024).
The choice of models for our experiments is currently dictated by the sensitive nature of
our data. To extend the choice from open source to proprietary models, we are currently
collecting a "pseudo-corpus" with fictitious personal information that we will
be able to share freely for future research (you are welcome to contribute to the
pseudo-corpus collection<https://forms.gle/t4ynDJwqfmFXYitPA> as well).
Finally, in this talk I will name several strategies to unify the research on automatic
pseudonymization, and outline further
challenges, needs for standardization and a proposal of a shared task.
