The extensive effort of cultural institutions in digitizing historical archival materials and distributing them through online digital archives have significantly enhanced the study of historical figures. However, current historical digital archives, which rely on keyword-based search methods, often return numerous but imprecise results making it challenging for historians to understand chronological and contextual events surrounding a historical figure. We would like to present the result of the Mini-Muse project. It was a preliminary research project aimed at identifying data visualization models and user-friendly interface features to help historians visually explore historical figures and their actions. The project leverages Natural Language Processing (NLP) algorithms to extract metadata from unstructured text and generate structured data about key figures. It also applies data visualization techniques to support the visual analysis of each figure's timeline. The project adopts a user-centered design approach to ensure that the user interface features meet the needs of historians. It involves a pool of Swiss and Italian historians to gather insights on their research practices and validate a working prototype. The findings of the preliminary research project suggests that the introduction of an ''action flow view'', an interactive timeline displaying the historical figure's actions extracted automatically, can significantly improve the identification and study of historical figures.Attribution 4.0 International LicenseCCS Concepts: Information systems → Web interfaces; Users and interactive retrieval; Digital libraries and archives; Human-centered computing → Human computer interaction (HCI); Graphical user interfaces; Interaction design; Visualization systems and tools; Computing methodologies → Natural language processingInformation systems → Web interfacesUsers and interactive retrievalDigital libraries and archivesHuman centered computing → Human computer interaction (HCI)Graphical user interfacesInteraction designVisualization systems and toolsComputing methodologies → Natural language processing10.2312/dh.202531504 pages
