SPARQL with Property Paths

, 2015
The original SPARQL proposal was often criticized for its inability to navigate through the structure of RDF documents. For this reason property paths were introduced in SPARQL 1.1, but up to date there are no theoretical studies examining how their addition to the language affects main computational tasks such as query evaluation, query containment ...

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

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
