Modeling Interactions from Email Communication

Daniel Gatica-Perez, Samy Bengio, Dong Zhang

Email plays an important role as a medium for the spread of information, ideas, and influence among its users. We present a framework to learn topic-based interactions between pairs of email users, i.e., the extent to which the email topic dynamics of one ...

An Ontology of Virtual Humans: Incorporating Semantics into Human Shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

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 ...

Acquiring, structuring shapes and annotating them with semantics to improve design activities

Daniel Thalmann, Frédéric Vexo

Shapes incorporate geometry as well as semantics and can be defined in 2D, 3D or higher dimensions. Geometric models can be structured in such a way that they can provide a relevant framework to insert semantic information or view dependent information abo ...

Towards P2P-based Semantic Web Service Discovery with QoS Support

Karl Aberer, Manfred Hauswirth

The growing number of web services advocates distributed discovery infrastructures which are semantics-enabled and support quality of service (QoS). In this paper, we introduce a novel approach for semantic discovery of web services in P2P-based registries ...

Semantic virtual environments

The main problem targeted by this research is the lack of flexibility of virtual objects within a Virtual Environment. Virtual objects are difficult to re-use in applications or contexts different from the ones they were designed for. This refers mainly to ...

Extracting Information from Multimedia Meeting Collections

Daniel Gatica-Perez, Samy Bengio, Dong Zhang

Multimedia meeting collections, composed of unedited audio and video streams, handwritten notes, slides, and electronic documents that jointly constitute a raw record of complex human interaction processes in the workplace, have attracted interest due to t ...

Finding groups of people in Google news

Daniel Gatica-Perez

In this paper, we study the problem of content-based social network discovery among people who frequently appear in world news. Google news is used as the source of data. We describe a probabilistic framework for associating people with groups. A low-dimen ...

Semantic Virtual Environments with Adaptive Multimodal Interfaces

Daniel Thalmann, Frédéric Vexo

We present a system for real-time configuration of multimodal interfaces to Virtual Environments (VE). The flexibility of our tool is supported by a semantics-based representation of VEs. Semantic descriptors are used to define interaction devices and virt ...

Concept expansion using semantic fisheye views

Pearl Pu Faltings, Vincent Jean Fabrice Schickel

Exploratory search over a collection often requires users to iteratively apply a variety of strategies, such as searching for more general or more specific concepts in reaction to the information they encounter. Rich semantic models, such as WordNet, are p ...
