Sparql-Ld: A Sparql Extension For Fetching And Querying Linked Data

Proceesings of the 14th International Semantic Web Conference - Demonstrations Track (ISWC'15), 2015
SPARQL is a standard query language for retrieving and manipulating RDF data. However, the majority of SPARQL implementations require the data to be available in advance, i.e., to exist in main memory or in a RDF repository (accessible through a SPARQL endpoint).

Metaverse and Artificial Intelligence as Web 4.0: The Next Generation of the Internet

Systems Research and Behavioral Science, EarlyView.
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.

Answering SPARQL queries modulo RDF Schema with paths [PDF]

, 2013
SPARQL is the standard query language for RDF graphs. In its strict instantiation, it only offers querying according to the RDF semantics and would thus ignore the semantics of data expressed with respect to (RDF) schemas or (OWL) ontologies.

PepeSearch: Semantic Data for the Masses. [PDF]

PLoS ONE, 2016
With the emergence of the Web of Data, there is a need of tools for searching and exploring the growing amount of semantic data. Unfortunately, such tools are scarce and typically require knowledge of SPARQL/RDF.

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 ...

Ontology‐driven intelligent assessment system for dam structural safety based on spatiotemporal anomaly detection framework

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 29, Page 5649-5671, 9 December 2025.
Abstract Dam safety assessment systems play a pivotal role in evaluating the structural integrity of critical hydraulic infrastructures. Current implementations frequently exhibit limitations in critical functionalities including multi‐source data integration and automated anomaly detection.

A hands-on introduction to querying evolutionary relationships across multiple data sources using SPARQL [version 2; peer review: 1 approved, 2 approved with reservations]

F1000Research, 2020
The increasing use of Semantic Web technologies in the life sciences, in particular the use of the Resource Description Framework (RDF) and the RDF query language SPARQL, opens the path for novel integrative analyses, combining information from multiple ...

Intelligent SPARQL Query Generation for Natural Language Processing Systems

IEEE Access, 2021
Developing question answering (QA) systems that process natural language is a popular research topic. Conventionally, when QA systems receive a natural language question, they choose useful words or phrases based on their parts-of-speech (POS) tags.

The women honoured in flowering plant genera: From myth to reality

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1845-1857, November 2025.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...

Context-Free Path Queries on RDF Graphs

, 2016
Navigational graph queries are an important class of queries that canextract implicit binary relations over the nodes of input graphs. Most of the navigational query languages used in the RDF community, e.g.
