Sampo Model and Series of Semantic Portals
This page presents the ”Sampo” model and series of Linked Open Data services and semantic portals (Hyvönen, 2021), based on six principles:
- Support collaborative data creation and publishing.
- Use a shared open ontology infrastructure.
- Support data analysis and knowledge discovery in addition to data exploration.
- Provide multiple perspectives to the same data.
- Standardize portal usage by a simple filter-analyze two-step cycle.
- Make clear distinction between the Linked Open Data service and the user interface (UI).
Sampo portal data services are provided by the Linked Data Finland platform. For the user interfaces, the Sampo-UI framework (Ikkala et al., 2021) has been used in recent Sampos online.
The Sampo portals listed below in the table have had millions of end users on the Web in total, suggesting feasibility and sustainability of the approach that has evolved gradually since 2002. The video below overvies the general idea on using Artificial Intelligence in Digital Humanities related to our work on the Sampo systems.
The Sampo model with the underlying Linked Open Data infrastructure in Finland are explained in the keynote presentation at the DCMI 2021 conference below:
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 (Hyvönen, 2020). 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.
