As a case study we use the BiographySampo knowledge graph which includes life events extracted from the short biographies of 13 100 prominent historical persons in Finland. We use SPARQL CONSTRUCT queries to extract connections and create human readable explanations based on the events in the knowledge graph, and then offer faceted search tools to search and filter the connections. The results can then be visualized using various charts and maps.9engcc_byinfo:eu-repo/semantics/openAccessComputer and information sciencesLanguagesConference contributionopenAccess19c9d802-a8ea-4460-b39b-a2bb1ccf875685168663729
