Integrating Semantics into Research Data Management: Modelling and Validating Materials Science Experiment Workflows
Samuel García Vázquez, Victor Dudarev, Alfred Ludwig +2
The incorporation of Semantic Web technologies within scientific environments is becoming an increasingly popular Research Data Management (RDM) practice. While ontologies offer fl…
Cardinality Estimation over Knowledge Graphs with Embeddings and Graph Neural Networks
Tim Schwabe, Maribel Acosta
Cardinality Estimation over Knowledge Graphs (KG) is crucial for query optimization, yet remains a challenging task due to the semi-structured nature and complex correlations of ty…
Consistent data fusion with Parker
Antoon Bronselaer, Maribel Acosta
When combining data from multiple sources, inconsistent data complicates the production of a coherent result. In this paper, we introduce a new type of constraints called edit rule…
A Framework for Federated SPARQL Query Processing over Heterogeneous Linked Data Fragments
Lars Heling, Maribel Acosta
Linked Data Fragments (LDFs) refer to Web interfaces that allow for accessing and querying Knowledge Graphs on the Web. These interfaces, such as SPARQL endpoints or Triple Pattern…
A Software Framework and Datasets for the Analysis of Graph Measures on RDF Graphs
Matthäus Zloch, Maribel Acosta, Daniel Hienert +2
As the availability and the inter-connectivity of RDF datasets grow, so does the necessity to understand the structure of the data. Understanding the topology of RDF graphs can gui…
RDF-Hunter: Automatically Crowdsourcing the Execution of Queries Against RDF Data Sets
Maribel Acosta, Elena Simperl, Fabian Flöck +2
In the last years, a large number of RDF data sets has become available on the Web. However, due to the semi-structured nature of RDF data, missing values affect answer completenes…
