Abstract
This paper introduces Koala-UI – a user interface system aimed at simplifying the entity linking process within data enrichment pipelines. Koala-UI provides an intuitive mechanism for linking entities across datasets, combining automation with human feedback to ensure accurate and consistent data. Koala-UI was successfully applied in use cases such as public procurement, where it enabled enrichment of a tenders dataset by linking entities to external knowledge graphs. Future developments will focus on expanding its backend to support additional models and enhance its human-in-the-loop capabilities.
