WarSampo publishes massive collections of heterogeneous, distributed data about the WW2 on the Semantic Web. The datasets are harmonized using event-based modeling and are enriched semantically with each other’s contents and external data. WarSampo has two components: 1) WarSampo Linked Open Data service of over 9M triples for Digital Humanities research and for creating applications. 2) WarSampo Semantic Portal, based on the data service, allowing both historians and laymen to study war history and destinies of their family members in the war from 7 interlinked perspectives. The portal had nearly 20,000 visitors during the first few days after its publication.
WHAT IS WARSAMPO?
According to Georg Wilhelm Friedrich Hegel “we learn from history that we learn nothing from history”. The ultimate goal of WarSampo is to prove that he was wrong. We believe that peace can be promoted by making reliable data about the war openly available for everybody to learn. The WarSampo system and project is motivated and described at the home page http://seco.cs.aalto.fi/projects/sotasampo/en/ including links to additional videos, short descriptions of the datasets, of the modeling principles, and of the implementation. There is also a description of the underlying national consortium of the participating organizations in the initiative. WarSampo is part of the Centenary of Finland’s Inpendence 2017 programme, coordinated by the Prime Minister’s office.
LINKED OPEN DATA SERVICE AND APPLICATION PORTAL
The WarSampo end-user portal is available at http://www.sotasampo.fi/en/ and the underlying Linked Open Data service at http://www.ldf.fi/dataset/warsa The data in use is in Finnish but the graphical user interface is available in English, too.
WarSampo is based on rigorous scientific technological research that has been reported in 11 international papers and theses in 2015-2017. These publications (listed below) are available online at the end of the WarSampo homepage for more detailed descriptions of the system and its data:
