Suomalaiset sotavangit 1939-1945 Neuvostoliitossa
|
Perjantaina 29.11.2019, klo 14:00–15:30
Kansallisarkisto, Vanha tutkijasali, Rauhankatu 17, Helsinki
Tilaisuudessa avataan ja esitellään talvisodan 80-vuotismuiston kunniaksi Sotasammon uusi, linkitettyyn avoimeen dataan perustuva sovellus "Suomalaiset sotavangit Neuvostoliitossa 1939-1945". Sotasampo on suomalaisia toisen maailmansodan aineistoja yhdistävä ja julkaiseva, semanttiseen webiin perustuva data- ja verkkopalvelu. Sotasampo julkaistiin syksyllä 2015 ja se sai kesällä 2017 kansainvälisen LODLAM Challenge Open Data Prize -palkinnon Venetsiassa. Palvelulla on ollut tähän mennessä (29.11.2019) n. 570 000 käyttäjää verkossa, eli n. joka kymmenes suomalainen on vieraillut Sotasammossa.
Pilottisovellus verkossa
Sotasammon uusi Sotavangit-sovellus on tarkoitettu sekä suuren yleisön että tutkijoiden käytettävksi. Jokaiselle sotavangille on tehty automaattisesti "kotisivu", johon on linkitetty kaikki häneen liittyvät tiedonmuruset. Aineistot tarjoillaan käyttäjälle uutena, yhdeksäntenä sovellusnäkymänä Sotasammossa. Näkymä tarjoaa älykkään hakuliittymän sotavankiaineistoon ja mahdollisuuden selata, analysoida ja visualisoida aineistoja digitaalisten ihmistieteiden keinoin. Sovellus avataan osoitteessa:
Tutkimushanke taustalla
Uusi sovellus on ideoitu, suunniteltu ja toteutettu Aalto-yliopiston ja Helsingin yliopiston HELDIG-keskuksen Semanttisen laskennan tutkimusryhmässä (SeCo) yhteistyössä Kansalliarkiston ja Sotavainajien muiston vaalimisyhdistyksen asiantuntijoiden kanssa Kaatuneiden muistosäätiön rahoituksella. Järjestelmä on uusi jäsen kansainvälisesti ja kotimaassa palkittujen semanttisen webin "Sampo"-portaalien sarjassa ja hyodyntää kansallista semanttisen webin infrastruktuuria LODI4DH.
Hanke käynnistyi v. 2016 Sotavainajien muiston vaalimisyhdistys ry:n (SMVY) ja Kansallisarkiston (KA) toimesta tavoitteena täydentää ja julkaista avoimena datana tiedot viime sotiemme suomalaisista sotavangeista nykyisten rajojemme ulkopuolella. Projekti toteutettiin Sotasammon kehittäneen Semanttisen laskennan tutkimusryhmän (SeCo) kanssa, koska järkevintä on tuottaa uudesta sotavankeihin liittyvästä datasta suoraan linkitettyä dataa Sotasammon ontologiainfrastruktuuria hyödyntäen. Näin uusi data automaattisesti rikastuu Sotasammon muiden aineistojen kautta 'ilmaiseksi', ja toisaalta uusi data rikastaa Sotasammossa jo julkaistujen aineistojen sisältöä 'Sampo' mallin idean mukaisesti.
Lisätietoa hankkeesta löytyy projektin kotisivulta.

This paper presents first results of a new, ninth application perspective for the semantic portal WarSampo - Finnish WW2 on the Semantic Web, based on a database of ca. 4450 Finnish prisoners of war in the Soviet Union. Our key idea is to reassemble the life of each prisoner of war by using Linked Data, based on information about the person in different data sources. Using the enriched aggregated data, a biographical global home page for each prisoner of war can be created, that is more complete than information in individual data sources. The application perspective is targeted to researchers of military history, to study and analyze the data in order to form new research questions or hypotheses, as well as to public in the large looking for information e.g., about their relatives that were captured as prisoners of war. Employing the faceted search of the application perspective, prosopographical research on subgroups of prisoners is possible.

The Second World War (WW2) is arguably the most devastating catastrophe of human history, a topic of great interest to not only researchers but the general public. However, data about the Second World War is heterogeneous and distributed in various organizations and countries making it hard to utilize. In order to create aggregated global views of the war, a shared ontology and data infrastructure is needed to harmonize information in various data silos. This makes it possible to share data between publishers and application developers, to support data analysis in Digital Humanities research, and to develop data-driven intelligent applications. As a first step towards these goals, this article presents the WarSampo knowledge graph (KG), a shared semantic infrastructure, and a Linked Open Data (LOD) service for publishing data about WW2, with a focus on Finnish military history. The shared semantic infrastructure is based on the idea of representing war as a spatio-temporal sequence of events that soldiers, military units, and other actors participate in. The used metadata schema is an extension of CIDOC CRM, supplemented by various military historical domain ontologies. With an infrastructure containing shared ontologies, maintaining the interlinked data brings upon new challenges, as one change in an ontology can propagate across several datasets that use it. To support sustainability, a repeatable automatic data transformation and linking pipeline has been created for rebuilding the whole WarSampo KG from the individual source datasets. The WarSampo KG is hosted on a data service based on W3C Semantic Web standards and best practices, including content negotiation, SPARQL API, download, automatic documentation, and other services supporting the reuse of the data. The WarSampo KG, a part of the international LOD Cloud and totalling ca. 14 million triples, is in use in nine end-user application views of the WarSampo portal, which has had over 400 000 end users since its opening in 2015.

Semantic data integration from heterogeneous, distributed data silos enables Digital Humanities research and application development employing a larger, mutually enriched and interlinked knowledge graph. However, data integration is challenging, involving aligning the data models and reconciling the concepts and named entities, such as persons and places. This paper presents a record linkage process to reconcile person references in different military historical person registers with structured metadata. The information about persons is aggregated into a single knowledge graph. The process was applied to reconcile three person registers of the popular semantic portal WarSampo -- Finnish World War 2 on the Semantic Web . The registers contain detailed information about some 100,000 people and are individually maintained by domain experts. Thus, the integration process needs to be automatic and adaptable to changes in the registers. An evaluation of the record linkage results is promising and provides some insight into military person register reconciliation in general.

WarSampo Knowledge Graph includes harmonized data of different kinds concerning the Second World War in Finland, separated in different subgraphs representing events, actors, places, photographs, and other aspects and documentation of the war. The data covers the Winter War 1939-1940 against the Soviet attack, the Continuation War 1941-1944 where the occupied areas of the Winter War were temporarily regained, and the Lapland War 1944-1945, where the Finns pushed the German troops away from Lapland.

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.

One of the great promises of Linked Data and the Semantic Web standards is to provide a shared data infrastructure into which more and more data can be imported and aligned, forming a sustainable, ever growing knowledge graph or linked data cloud, Web of Data. This paper studies and evaluates this idea in the context of the WarSampo Linked Data cloud, providing an infrastructure for data related to the Second World War in Finland. As a case study, a new database of prisoners of war with related contents is transformed into linked data and integrated into WarSampo. Lessons learned are discussed in relation to using traditional data publishing approaches.
