KupferDigital: Ontology‐Based Digital Representation for the Copper Life Cycle

Advanced Engineering Materials, Volume 27, Issue 8, April 2025.
It is demonstrated how data from different stages in the life cycle of a copper product can be stored in an ontology‐based data space. In order to showcase the methods and tools used in the project, four use cases are presented that show how data from different sources can be semantically described and queried from a shared data space.

SPARQL with property paths on the Web

Semantic Web, 2017
Linked Data on the Web represents an immense source of knowledge suitable to be automatically processed and queried. In this respect, there are different approaches for Linked Data querying that differ on the degree of centralization adopted. On one hand, the SPARQL query language, originally defined for querying single datasets, has been enhanced with

An empirical performance evaluation of a semantic-based data retrieving process from RDBs & RDF data storages

Maskana, 2017
SQL and, more recently, SPARQL are standard languages of the software industry for retrieving data. Other studies showed that retrieving data by using a SPARQL query is much slower than the semantically equivalent SQL query.

Killing Two Birds with One Stone -- Querying Property Graphs using SPARQL via GREMLINATOR [PDF]

arXiv, 2018
Knowledge graphs have become popular over the past decade and frequently rely on the Resource Description Framework (RDF) or Property Graph (PG) databases as data models. However, the query languages for these two data models -- SPARQL for RDF and the PG traversal language Gremlin -- are lacking interoperability.

Broadband Spectroscopy and Interferometry with Undetected Photons at Strong Parametric Amplification

Advanced Quantum Technologies, Volume 8, Issue 4, April 2025.
An SU(1,1) interferometer with an aperiodically poled lithium niobate crystal to demonstrate broadband Fourier‐transform spectroscopy (FTS) and high‐resolution optical coherence tomography (OCT) with undetected photons in the high‐gain regime is developed.

Pemanfaatan Linked Data untuk Meningkatkan Kualitas Information Knowledge pada Resources Game Online

Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2017
This paper proposes an online game design that has resources with interoperability. Interoperability means the resources can share, re-used, and interlinked with another Unified Resources Identifier (URI).

Subsumption of Weakly Well-Designed SPARQL Patterns is Undecidable [PDF]

arXiv, 2019
Weakly well-designed SPARQL patterns is a recent generalisation of well-designed patterns, which preserve good computational properties but also capture almost all patterns that appear in practice. Subsumption is one of static analysis problems for SPARQL, along with equivalence and containment. In this paper we show that subsumption is undecidable for
