Towards a new vision of PaNET: enhancing reasoning capabilities for better photon and neutron data discovery

Journal of Synchrotron Radiation, Volume 32, Issue 5, Page 1361-1369, September 2025.
This evolution of PaNET builds on the initial foundational work, which established the infrastructure and incorporated domain expert knowledge, by introducing logical frameworks that provide enhanced reasoning capabilities, and is proposed to address the limitations of the current version of the ontology. This under‐the‐hood development has resulted in

SPARQL playground: A block programming tool to experiment with SPARQL [PDF]

, 2015
SPARQL is a powerful query language for Semantic Web data sources but one which is quite complex to master. As the block programming paradigm has been succesfully used to teach programming skills, we propose a tool that allows users to build and run SPARQL queries on an endpoint without previous knowledge of the syntax of SPARQL and the model of the ...

Using linked data for data analytic literary research: Case BookSampo—Finnish fiction literature on the semantic web

Journal of the Association for Information Science and Technology, Volume 76, Issue 7, Page 937-958, July 2025.
Abstract The BookSampo Linked Data portal was deployed in 2011 by the Finnish Public Libraries and has today nearly 2 million annual users. Its Linked Data covers virtually all Finnish fiction literature but the data has not been used for data analyses in Digital Humanities. This paper discusses how the Knowledge Graph can be used for literary research
