Novel Visualizations and Interactions for Social Networks Exploration


Collecting data to understand how people communicate, collaborate, what
information they exchange, what role they play in social groups has been
tremendously simplified with the popularity of online networking systems
such as Friendster, LinkedIn, or Facebook. Compared to data collected
through polls and interviews, collected networks require less processing as
they are directly stored digitally and open new opportunities for social
scientists as they are far larger and often contain much richer information.
However, this avalanche of data raises new challenges for their analysis:
tools need to support a very large amount of data often evolving through
time.



As human brain is particularly effective at processing visual information,
researchers in computer science developed a number of visual exploration
system to analyze graphs and networks. In the last five years, an increasing
part of the research in information visualization focused on graph
visualization, tackling the problem from novel angles. Our research focused
on alternative representations to node-link diagrams, supporting the
analysis of denser networks as well as novel interaction techniques to scale
to larger datasets. In this talk, I will present an overview of these novel
visual exploration systems.



Bio:

Nathalie is a researcher at Microsoft Research since december 2008.
Her interests lie in the visual exploration of graphs and networks,
visualization of groups, interactive graph navigation techniques and
evaluation methods for information visualization. She completed her Ph.D on
the visual exploration of social networks in 2008, supervised by Pr.
Jean-Daniel Fekete in France and Pr. Peter Eades in Australia.

Exciting projects she is involved in at MSR include the visualization of
heterogeneous networks (multiple types of nodes and edges), the
visualization of networks evolving over time, and taking advantage of
natural user interactions (sketch, natural language) to create and interact
with visualizations.
