“The WarSampo system 1) initiates and fosters large scale Linked Open Data (LOD) publication of WW2 data from distributed, heterogeneous data silos and 2) demonstrates and suggests its use in applications and DH research. WarSampo is to our best knowledge the first large scale system for serving and publishing WW2 LOD on the Semantic Web for machine and human users. Its knowledge graph metadata contains over 9 million associations (triples) between data items including, e.g., a complete set of over 95,000 death records of Finnish WW2 soldiers, 160,000 authentic photos taken during the war, 32,000 historical places on historical maps, 23,000 war diaries of army units, and 3,400 memoir articles written by the veterans after the war. WarSampo data comes from several Finnish organizations and sources, such as National Archives, Defense Forces, Land Survey of Finland, Wikipedia/DBpedia, text books, and magazines.
WarSampo has two separate components: 1) WarSampo Data Service for machines and 2) WarSampo Semantic Portal with various applications for human users.”
