A Case Study on the Use of Semantic Web Technologies for Learner Guidance

Andrea Zielinski, Jürgen Bock
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
Using a real-world case study from the eLearning domain, we compare an OWL 2 DL implementation with an equivalent graph algorithm implementation with respect to time efficiency.  ...  We claim that in a dynamically changing environment, where the computation of reachability of a vertex is computed on demand at run-time, OWL-based reasoning does not scale up well.  ...  Acknowledgments: The research leading to these results has received funding from the EC's 7 th Framework Programme (FP7/2007-2013) under grant agreement N 318496.  ...

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  
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.  ...  These knowledge bases integrate both data, like Kegg, and ontologies, like Gene Ontology, in the same RDF graphs.  ...  Conclusion The use of MDGs, annotated with terms about relations in Metarel, enables a bridge between graphbased representations like RDF and DL-based representations like OWL.  ...

2009 Zenodo  
The purpose of this paper is to study Database Models to use them efficiently in E-commerce websites.  ...  Noting that a large number of semantic webs get advantage of relational model, opening the ways which can be converted to XML and RDF in modern systems (semantic web) is important.  ...  OWL, originally created for the Semantic Web enables us to represent not only the relational data itself, but also a part of its interpretation, i.e. knowledge about its format, its origin, its usage,  ...
