Utility of Ontology Extraction Tools in the Hands of Educators
Found in: International Conference on Semantic Computing
By Marek Hatala, Dragan Gasevic, Melody Siadaty, Jelena Jovanovic, Carlo Torniai
Issue Date:September 2009
pp. 408-413
We present results of the end user study evaluating tools that use two distinct approaches to developing ontology from text material. Our aim was to examine a current state of support for a widespread assumption in many semantic web application domains, su...

<p>This article presents a framework for automatic semantic annotation of video streams with an ontology that includes concepts expressed using linguistic terms and visual data.</p>
 
Leveraging Folksonomies for Ontology Evolution in E-learning Environments
Found in: International Conference on Semantic Computing
By Carlo Torniai, Jelena Jovanovic, Scott Bateman, Dragan Gaševic, Marek Hatala
Issue Date:August 2008
pp. 206-213
One of the main obstacles for wider adoption of semantic rich e-learning systems is the difficulty in creating and maintaining domain ontologies describing courses. Annotations, such as those resulting from collaborative tagging, provide a new source of in...
 
E-Learning meets the Social Semantic Web
Found in: Advanced Learning Technologies, IEEE International Conference on
By Carlo Torniai, Jelena Jovanovic, Dragan Gaševic, Scott Bateman, Marek Hatala
Issue Date:July 2008
pp. 389-393
The Social Semantic Web has recently emerged as a paradigm in which ontologies (aimed at defining, structuring and sharing information) and collaborative software (used for creating and sharing knowledge) have been merged together. Ontologies provide an ef...

Enhanced ontologies for video annotation and retrieval
Found in: Proceedings of the 7th ACM SIGMM international workshop on Multimedia information retrieval (MIR '05)
By Alberto Del Bimbo, Carlo Torniai, Marco Bertini
Issue Date:November 2005
