Metaverse and Artificial Intelligence as Web 4.0: The Next Generation of the Internet
Systems Research and Behavioral Science, Volume 43, Issue 2, Page 826-844, March/April 2026.ABSTRACT This study utilizes systems thinking to explore and entwine an evolving metaverse scholarship to a relatively underexplored phenomenon of Web 4.0. We adopt a soft systems thinking framework to guide the interpretation of complex and evolving metaverse scholarship, using bibliometric mapping of 5587 publications sourced from Scopus.

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 ...

On the Formulation of Performant SPARQL Queries [PDF]
SSRN Electronic Journal, 2015 The combination of the flexibility of RDF and the expressiveness of SPARQL provides a powerful mechanism to model, integrate and query data. However, these properties also mean that it is nontrivial to write performant SPARQL queries. Indeed, it is quite easy to create queries that tax even the most optimised triple stores.

FAIR Workflows in Earth System Modelling: A Use Case With Semantic Data Management
Geoscience Data Journal, Volume 13, Issue 1, January 2026.We present a semantic research data management workflow that enables the re‐use of legacy simulation datasets in accordance with FAIR principles. The approach integrates automated semantic annotation, queryable data access, and a connected JupyterHub for FAIR‐compliant output analysis and storage of derived results. ABSTRACT The amount of research data

SPARQL extensions with preferences [PDF]
Proceedings of the 31st Annual ACM Symposium on Applied Computing, 2016 The last decade has witnessed an increasing interest in expressing preferences inside database queries. Even though most of the work has been devoted to relational databases, many proposals have also been made in the Semantic Web area in order to query RDF databases in a flexible way.

Three Algorithms for Parallel Graph Summarization
Expert Systems, Volume 43, Issue 1, January 2026.ABSTRACT Most graph summarization algorithms are tailored to a specific graph summary model and were designed for one‐time computations only, that is, batch‐based computations. We developed a universal approach for parallel graph summarization and three algorithms to compute graph summaries—a batch‐based algorithm for static graphs, an incremental ...

SPARQL beyond Subgraph Matching. [PDF]
, 2010 We extend the Semantic Web query language SPARQL by defining the semantics of SPARQL queries under the entailment regimes of RDF, RDFS, and OWL. The proposed extensions are part of the SPARQL 1.1 Entailment Regimes working draft which is currently being ...
