Ontology learning for the Semantic Web

A. Maedche, S. Staab
2001 IEEE Intelligent Systems  
T he Semantic Web relies heavily on formal ontologies to structure data for comprehensive and transportable machine understanding.  ...  The vision of ontology learning that we propose includes a number of complementary disciplines that feed on different types of unstructured, semistructured, and fully structured data to support semiautomatic  ...  Acknowledgments We thank our students, Dirk Wenke, and Raphael Volz for work on OntoEdit and Text-To-Onto.  ...

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  
In this paper, we propose transformation rules for building owl ontology from the RDB of the open source LMS Moodle. It allows transforming all possible cases in RDBs into ontological constructs.  ...  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.  ...

A Semantic-based Variables Selection for Ontology Learning Taking Jaccard Alignment as Case

Djellali Choukri
2014 Procedia Computer Science  
In the past decade, research on numerical schemes on ontology learning has been quite intensive. Several learning approaches have been proposed to help developers during the maintenance process.  ...  A novel semantic-based method for ontology learning, which can provide improvement in both alignment and learning, is described.  ...  In this study, we propose a new conceptual model for ontology learning based on variables selection, clustering and an alignment process.  ...

A Model-Driven Approach of Ontological Components for On-line Semantic Web Information Retrieval

Hajer Baazaoui Zghal, Marie-Aude Aufaure, Nesrine Ben Mustapha
2007 Journal of Web Engineering  
Ontologies specify the knowledge shared by a community of a target domain in an explicit and formal way. The present work deals with the problem of ontology construction for the Semantic Web.  ...  The objective of the paper is to propose a solution for the representation of Web knowledge by means of ontologies as well as to define an approach to their semi-automatic construction.  ...  It is a conceptualization of the semantic related to Web sites structure.  ...

Measuring mental models: Rationales and instruments

Yan Zhang, Peiling Wang
2006 Proceedings of the American Society for Information Science and Technology  
For more and more end users, this is the first IR system they learn. Their mental models of the Web will likely affect their behaviors when using other types of IR systems.  ...  There are often more than one user views targeting different user groups. Typically, one for novices and one for advanced users.  ...  • The Web's structure This category measures users' understanding of how information objects on the Web are organized for access.  ...
