This chapter investigates how metadata can be enriched to improve the usability Linked Open Data (LOD) in Digital Humanities research. It reviews successive case studies based on semantic Sampo LOD services and portals in Finland that enable searching, browsing, and analysing parliamentary discussions, legislation and case law, art, historical letters, artefact collections, biographies, and enriched video content. The methodological framework utilises linked data technologies, ontologies, vector space models, Large Language Models (LLM), and Generative AI.
