Semantic Portal with Integrated DH Tools
WarVictimSampo 1914–1922 is a semantic portal and a Linked Open Data service that publishes data about the war victims in Finland in 1914–1922. The project is based on the database War Victims of Finland 1914–22 (“Sotasurmat 1914–22”) of the National Archives of Finland and related data compiled during the project. This database contains some 40 000 death records, most of which are due to the Finnish Civil War but some are related to the First World War and the Kindred Nations Wars. In addition to the war victims, our data includes information about 1200 battles of the Civil War and various prisoner camps. A key novelty of WarVictim-Sampo 1914–22 is the integration of ready-to-use Digital Humanities tooling with the data service, which allows, e.g., studying information about wider prosopographical groups in addition to individual victims.
A more detailed presentation of the system can be found in this paper.

This paper introduces AMMO Ontology of Finnish Historical Occupations. AMMO is based on thousands of occupation labels extracted from three Finnish military historical datasets of the early 20th century: the first consists of the ca. 40 000 war-related death records around the time of the Finnish Civil War (1914–1922); the second consists of the ca. 95 000 death records of Finnish soldiers in the Winter War and Continuation War (1939–1944); the third contains the ca. 4500 records of Finnish prisoners of war in the Soviet Union during the WW2. Our goal from a Digital Humanities perspective is to use AMMO to study military history and these datasets based on the occupation and social status of the soldiers. AMMO will also be used as a component for faceted search and semantic recommendation in two semantic portals for Finnish military history. AMMO is aligned with the international historical occupation classification HISCO and with a modern Finnish occupational classification for international and national interoperability. The ontology is published as Linked Open Data in an ontology service.

Historical datasets often impose the need to study groups of people based on occupation or social status. This paper presents first results in creating an ontology of historical Finnish occupations, AMMO, that enables selection of groups of people based on their occupation, occupational groups, or socioeconomic class. AMMO is linked to the international historical occupation classification HISCO and to a modern Finnish occupational classification for interoperability. AMMO will be used as a component in two semantic portals for Finnish war history.
