Context aware, multimodal, and semantic rendering engine

Daniel Thalmann, Patrick Salamin

Nowadays, several techniques exist to render digital content such as graphics, audio, haptic, etc. Unfortunately, they require different faculties that cannot always be applied, e.g. providing a picture to a blind person would be useless. In this paper, we ...

Conceptual modeling of multimedia databases

Oleksandr Drutskyy

The gap between the semantic content of multimedia data and its underlying physical representation is one of the main problems in the modern multimedia research in general, and, in particular, in the field of multimedia database modeling. We believe that o ...

Visual creation of inhabited 3D environments: An ontology-based approach

Daniel Thalmann, Alejandra Garcia Rojas Martinez

The creation of virtual reality applications and 3D environments is a complex task that requires good programming skills and expertise in computer graphics and many other disciplines. The complexity increases when we want to include complex entities such a ...

The AMGA Metadata Service

Nuno Filipe de Sousa Santos

We present the AMGA metadata catalogue, which was developed as part of the EGEE (enabling Grids for EsciencE) project's gLite Grid middleware. AMGA provides access to metadata for files stored on the Grid, as well as a simplified general access to relation ...

Towards a Scientific Model Management System

Stefano Spaccapietra, José Antonio Fernandes de Macedo

Computational models of biological systems aim at accurately simulating in vivo phenomena. They have become a very powerful tool enabling scientists to study complex behavior. A side effect of their success Unfortunately exists and is observed as an increa ...

Critical Sections: Re-Emerging Scalability Concerns for Database Storage Engines

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Critical sections in database storage engines impact performance and scalability more as the number of hardware contexts per chip continues to grow exponentially. With enough threads in the system, some critical section will eventually become a bottleneck. ...

Methods of inferring user preferences using ontologies

Boi Faltings, Vincent Jean Fabrice Schickel

Methods of inferring user preferences using ontologies use ontology structure based similarity and an inference mechanism in defining ontology filtering (OF). Items are recommended to users by identifying items that the users may prefer, but may not have b ...

Extending OWL with Explicit Dependency

Jean Paul Calbimonte Perez

Functional Dependency has been extensively studied in database theory. It provides an elegant formalism for specifying key constraints and is the basis for normalization theory used in Relational database design. Given its known axiomatization through logi ...

An ontology of virtual humans: Incorporating semantics into human shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez, Laurent Moccozet

Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...
