Semantic data are gaining increasing relevance within the fields of Cultural Heritage (CH) and Digital Humanities
(DH). Despite their considerable promise and potential, however, these technologies currently tend to introduce
additional challenges rather than effectively resolving existing ones. A central issue lies in the limited availability
of graphical user interfaces that enable individuals with little prior knowledge of semantic data to explore them
through clear, accessible, and easily customizable visualizations. To address this challenge and facilitate broader
access to the insights embedded in semantic data, this paper presents methods from the field of Human-Computer
Interaction (HCI) and applies them to concrete examples from CH and DH. In particular, the study adopts a HumanCentered Design (HCD) approach, systematically examining the target user group and its needs, identifying
recurring issues in existing visualizations of the CIDOC Conceptual Reference Model (CIDOC CRM), and deriving
the tasks and requirements for a novel user interface (UI). Based on these analyses, the paper introduces a newly
designed UI sketch and justifies its design decisions with reference to established principles from Information
Visualization (InfoVis).
