How do data systems remember, forget, and represent the world?

I study how mechanistic interpretability can inform unlearning, alongside work on narrative unlearning, bias mitigation, Ukrainian NLP, and participatory data modeling.

Preprint: arXiv:2607.22657 · revised 31 July 2026.

LENS tests whether models reproduce targeted narratives across different prompting contexts, measuring suppression alongside degraded outputs.

Graph-Based Detection of Disinformation Narrative Diffusion between Russian and Ukrainian Telegram Channels

Yuliia Vistak, Viktoriia Makovska, Vera Schmitt, Veronika Solopova

In Proceedings of the Fifth Ukrainian Natural Language Processing Conference (UNLP 2026), pages 80-96, Lviv, Ukraine. Association for Computational Linguistics.

This work combines weak supervision with propagation-graph analysis to group semantically related claims and study how disinformation narratives move across Russian-language and Ukrainian-language Telegram channels.

Memory Undone: Between Knowing and Not Knowing in Data Systems

Viktoriia Makovska, George Fletcher, Julia Stoyanovich, Tetiana Zakharchenko

arXiv preprint arXiv:2602.21180 [cs.CY], submitted February 24, 2026. Presented at Undone Computer Science on 24 March 2026.

This position paper distinguishes erasure, unlearning, exclusion, and forgetting, and argues that machine unlearning should be evaluated not only by model utility but also by transparency, accountability, and governance.

ONION: A Multi-Layered Framework for Participatory ER Design

Viktoriia Makovska, George Fletcher, Julia Stoyanovich

In Proceedings of the Workshop on Human-In-the-Loop Data Analytics (HILDA '25), June 22, 2025, Berlin, Germany.

ONION is a five-stage participatory method for moving from unstructured stakeholder input to entity-relationship models while making assumptions, omissions, and designer choices easier to inspect.
