*Summary: *

In the recent years, the interactive aspects of the Internet became
increasingly important, transforming it into the main support for free
communication between potentially very different persons. This led to
considerable scientific and societal issues related to the supervision of
Web-based social interactions. Indeed, in order to work correctly, open
communication spaces need to be monitored, which is a difficult task.
Without any moderation, such a service can be hijacked, or end up hosting
negative behaviors decreasing the service quality, or even illegal
activities. One could argue the absence of any control actually contributed
to the development of such open spaces on the Web, however the absence of
any moderation could also dramatically limit their interest. Human-operated
moderation is often costly, and even economically unfeasible; creating
automatic monitoring methods for such large-scale textual interactions is
consequently of the highest interest. We propose to develop an approach
focused on users, and to evaluate it on the specific case of a social
networking service. Tackling this problem involves designing models of the
users’ behavior, and defining methods to estimate these statistical models.
The general framework of this PhD topic is social networks analysis.
