Axel Polleres, Aidan Hogan, Renaud Delbru, Jürgen Umbrich
2013 Lecture Notes in Computer Science  
We then introduce two high-level architectures for query answering over Linked Data and outline how these can be enriched by (lightweight) RDFS and OWL reasoning, enumerating the main challenges faced  ...  In this lecture we will show how reasoningusing RDF Schema (RDFS) and the Web Ontology Language (OWL)can help to obtain more complete answers for such queries over Linked Data.  ...  Pan, Luigi Sauro and Giovanni Tummarello.  ...

Integrating Linked Data through RDFS and OWL: Some Lessons Learnt [chapter]

Aidan Hogan
2011 Lecture Notes in Computer Science  
In this paper, we summarise the lessons learnt from the PhD Thesis Exploiting RDFS and OWL for Integrating Heterogeneous, Large-Scale, Linked Data Corpora where we looked at three use-cases for reasoning  ...  We summarise how we overcome the challenges of scalability and robustness faced when reasoning over Linked Data.  ...  Acknowledgements: I would like to thank to my supervisor Axel Polleres and my examiners Stefan Decker and James Hendler for their support.  ...

OWL: Yet to arrive on the Web of Data? [article]

Birte Glimm and Aidan Hogan and Markus Krötzsch and Axel Polleres
2012 arXiv   pre-print
likely to be a simplified profile based on OWL RL, (3) propose and discuss such a new fragment, which we call OWL LD (for Linked Data).  ...  This may suggest that despite the promise of easy implementations and the proposal of tractable profiles suggested in OWL's second version, there is still no "right" standard fragment for the Linked Data  ...  However, other OWL features are not mentioned. In terms of standards, RDFS and OWL 1 pre-date the Linked Data movement and are not directly tailored towards Linked Data requirements.  ...

RDF Reasoning on Large Ontologies: A Study on Cultural Heritage and Wikidata [chapter]

Nuno Freire, Diogo Proença
2020 IFIP Advances in Information and Communication Technology  
Our experiment on cultural data has shown that Wikidata contains alignment statements to other ontologies used in the cultural domain, which with the application of RDF and OWL reasoning can be used to  ...  Large ontologies are available as linked data, and they are used across many domains, but to process them considerable resources are required.  ...  We would like to acknowledge Antoine Isaac from the Europeana Foundation for his contribution to the preliminary discussion of our work regarding RDF reasoning and Wikidata.  ...

Using the relation ontology Metarel for modelling Linked Data as multi-digraphs

Ward Blondé, Erick Antezana, Vladimir Mironov, Stefan Schulz, Martin Kuiper, Bernard De Baets
2014 Semantic Web Journal  
The Semantic Web standards OWL and RDF are often used to represent biomedical information as Linked Data, however, the OWL/RDF syntax, which combines both, was never optimised for querying.  ...  They are especially useful in Linked Data and RDF knowledge bases that 1) rely on SPARQL querying and 2) require semantic support for chains of relations.  ...  Linked Data is data that is formatted in RDF for which the IRIs are dereferenceable through HTTP by web browsers and query services, which means that a representation can be retrieved for the IRI.  ...

OSLC Resource Shape: A language for defining constraints on Linked Data

Arthur G. Ryman, Arnaud Le Hors, Steve Speicher
2013 The Web Conference  
This paper explains the need for such a language, why standards like RDFS and OWL are not suitable answers and, finally, introduces OSLC Resource Shapes as a proposed solution.  ...  One such need is a type definition language that can be used to communicate and validate constraints on RDF data.  ...  ACKNOWLEDGMENTS This paper contains material and concepts that come from our work in OSLC and Arthur Ryman's Linked Data Interfaces article [22] .  ...
