A Novel Method for Generating an Elearning Ontology

Mohammed Reda Chbihi Louhdi, Hicham Behja, Said Ouatik El Alaoui
2013 International Journal of Data Mining & Knowledge Management Process  
The proposed rules are enriched by analyzing stored data to detect disjointness and totalness constraints in hierarchies, and calculating the participation level of tables in n-ary relations.  ...  The Semantic Web provides a common framework that allows data to be shared and reused across applications, enterprises, and community boundaries.  ...  ACKNOWLEDGMENTS We want to thank Misters Driss Goujdami and Abdelali Rochdi for providing us a dump file of the database of the pedagogical platform of the Cadi Ayyad University.  ...

SoftFacts: A top-k retrieval engine for ontology mediated access to relational databases

Umberto Straccia
2010 2010 IEEE International Conference on Systems, Man and Cybernetics  
An ontology layer is used to define (in terms of a OWL-QL like Semantic Web language) the relevant abstract concepts and relations of the application domain, while graded facts are stored into a relational  ...  We will illustrate SoftFacts' architecture, the representation and the query language, sketch the reasoning algorithms of the SoftFacts system and its Protégé plug-in.  ...  Clearly, in the Semantic Web context, data is typically very large and dominate the intentional level of the ontologies.  ...

Ontology-Based Approach For Temporal Semantic Modeling Of Social Networks

Souâad Boudebza, Omar Nouali, Faiçal Azouaou
2016 Zenodo  
Social networks have recently gained a growing interest on the web. Traditional formalisms for representing social networks are static and suffer from the lack of semantics.  ...  In this paper, we will show how semantic web technologies can be used to model social data.  ...  SemTemp defines the ternary relationship « semtemp : Knows_At » relating two persons « foaf :Person » with « time : interval ». Table V lists the n-ary relations of Semtemp ontology.  ...

Replacing the Monolithic LOM: A Folksonomic Approach

Hend S. Al-Khalifa, Hugh C. Davis
2007 Seventh IEEE International Conference on Advanced Learning Technologies (ICALT 2007)  
In this paper we show an approach that uses folksonomy tags to create structured metadata using semantic web technologies.  ...  To overcome this hurdle, we propose the use of cheap unstructured metadata to create structured semantic metadata, this metadata is called folksonomy.  ...  The subject-expert was asked to annotate a set of ten randomly chosen web resources from our data set using our three ontologies.  ...
