Fuzzy Logic Techniques in Multimedia Databases Querying: A Preliminary Investigation of the Potentials [chapter]

Didier Dubois, Henri Prade, Florence Sèdes
1999 Database Semantics  
Fuzzy logic is known for providing a convenient tool for interfacing linguistic categories with numerical data and for expressing user's preference in a gradual and qualitative way.  ...  This paper provides a preliminary investigation of the potential applications of fuzzy logic in multimedia databases. Querying issues are more particularly emphasized.  ...  Indeed, the flexibility of a query reflects the preferences of the end-user.  ...

Personalized Digital Item Adaptation in Service-Oriented Environments

Benjamin Kohncke, Wolf-tilo Balke
2006 2006 First International Workshop on Semantic Media Adaptation and Personalization (SMAP'06)  
The delivery of multimedia content often needs the adaptation of the content in order to satisfy user constraints.  ...  In the course of this paper we demonstrate this shortcoming and how the integration of more powerful models can ease the instantiation problem.  ...  In this paper we address the problem of adapting content in a personalized fashion by integrating MPEG-7/21 metadata with a complex preference framework, namely a model on qualitative partial order preferences  ...

High-Dimensional Indexing for Video Retrieval [chapter]

Catalin Calistru, Cristina Ribeiro, Gabriel Davi
2012 Multimedia - A Multidisciplinary Approach to Complex Issues  
Flexible ranking mechanisms that capture user preferences are also an important requirement.  ...  We show that our search strategy can cope with the trade-off between flexible video ranking, required for capturing the multitude of similarity facets, and query execution speed.  ...

Musical content-based retrieval

Pierre-Yves Rolland, Gailius Raškinis, Jean-Gabriel Ganascia
1999 Proceedings of the seventh ACM international conference on Multimedia (Part 1) - MULTIMEDIA '99  
Results obtained with Melodiscov were good and contrasted even more clearly with those of the other two systems using the same queries.  ...  Using a richer (more flexible) sequential similarity model with a richer representation of musical information, can result in an increase of the search stage's execution time.  ...

Towards an intelligent possibilistic web information retrieval using multiagent system

Bilel Elayeb, Fabrice Evrard, Montaceur Zaghdoud, Mohamed Ben Ahmed, Saïd Tazi
2009 Interactive Technology and Smart Education  
The insertion of the factors of preference between query terms in the calculations of the possibility and the necessity consists in increasing the scores of possibilistic relevance of the documents containing  ...  these terms with an aim of penalizing the scores of relevance of the documents not containing them.  ...  The network would be composed of sub-network of documents and of a sub-network of query terms. These sub-networks could be connected through ontology.  ...

A Multiagent System Architecture for QoS Management in Distributed Multimedia Systems [chapter]

Mamadou Tadiou Kone, Tatsuo Nakajima
2000 IFIP Advances in Information and Communication Technology  
Here agents are organized in a hierarchy along the components of the distributed multimedia system.  ...  Our idea in this model is to structure in an integrated and hierarchical fashion an adaptation strategy that span all the configurations made of components selected by a QoS manager.  ...  The original version of this chapter was revised: The copyright line was incorrect. This has been corrected. The Erratum to this chapter is available at DOI: 10.1007/978-0-387-35581-8 35  ...

Adopting Mobile Learning in Tertiary Environments: Instructional, Curricular and Organizational Matters

Boris Handal, Jean MacNish, Peter Petocz
2013 Education Sciences  
Teachers requested more professional development in a number of key areas including the integration of the technology into teaching and learning.  ...  This qualitative study looked at the instructional, curricular and organizational factors impacting on the adoption of mobile learning in a higher education institution.  ...  Sub-themes were coded into the initial categories of analysis, although some sub-themes were coded in several categories. As new sub-themes were coded, additional categories began to emerge.  ...
