Sampo Model and Series of Semantic Portals

This page presents the ”Sampo” model and series of Linked Open Data services and semantic portals, based on a 1) collaborative business model for publishing distributed heterogeneous contents, 2) a Semantic Web ontology and data infrastructure for making the contents semantically interoperable, 3) a model based on faceted search and data-analysis for solving research problems, and 4) the Sampo-UI framefork for creating user interfaces easily.

Sampo portals, such as CultureSampo, BookSampo, WarSampo, BiographySampo, NameSampo, and WarVictimSampo 1914–1922, have had millions of end users on the Web in total, suggesting feasibility and sustainability of the approach developed.

New Sampos Underway

At the moment several new Sampos are being developed. For example, FindSampo is a system targeted for archaeologists and citizen science metal detectorists using the collections of the Finnish Heritage Agency, including collaborations with the British Museum and the pan-European AriadnePlus project. LawSampo publishes Finnish legislation and case law on the Semantic Web in collaboration with the Ministry of Justice. The ParliamentSampo system is being developed in collaboration with the Parliament of Finland. Our goal is to publish Finnish parliamentary discussions and related data in an intelligent web service for researchers of political culture and the general public.

Paradigm Shift of Semantic Portals

The Sampo model and portals aim at making a paradigm change in publishing and using cultural heritage content on the Web. The contents are not only published as Linked Data but also integrated seamlessly with intelligent tools for data analysis. In our vision, AI should not only help the user in solving research problems, but also in finding new ones using Creative AI methods. We also focus on white box Explainable AI, which is important in humanities research.

In Douglas Adam’s novel “Hitchhiker’s Guide to the Galaxy”, the computer was asked “What is the meaning of life”. The answer “42” may be right, but a researcher in humanities would also like to know “why”.

Sampo Portal Series

The Sampo series of semantic portals is listed below.
