International visibility for COIN research: PhD student at ISWC 2025 in Japan

Sarah T. Bachinger, PhD student at the Heinz Nixdorf Chair for Distributed Information Systems in Jena and associate member of COIN, Germany, presented her dissertation project at the 24th International Semantic Web Conference (ISWC 2025) in Nara, Japan on November 3, 2025 as part of the Doctoral Consortium. With ten other PhD students from all over the world, she discussed her project "Examining the Representation of Uncertainty in Knowledge Graphs: A Case Study in Copolymer Chemistry", led by the consortium chairs Natasha Noy (Google Research) and Abraham Bernstein (University of Zurich). In her work, she aims to systematically map intrinsic uncertainties of chemical experiments in knowledge graphs. Through interviews with experts from copolymer chemistry, she will identify typical causes of uncertainty, such as incomplete measurement data or fluctuations in laboratory conditions. Based on this, she compares existing techniques for uncertainty representation in knowledge graphs and evaluates them based on chemistry-specific criteria. In the long term, Bachinger aims to develop a new method that models uncertainty more realistically. In doing so, she hopes to make predictions about the results of copolymer syntheses more precise – a crucial step towards planning experiments more efficiently and accelerating materials research.
