Title: INFORMATION EXTRACTION FOR SOCIAL MEDIA ANALYSIS

Speaker: Denilson Barbosa (University of Alberta, Edmonton, Canada)

Abstract:
More and more regular users use to blogosphere to express and discuss
their opinions, the facts, events, and ideas pertaining to their own
lives, their community, their profession, or society at large. It goes
without saying that being able to extract reliable data from this
medium opens the door to the most varied kinds of analysis and using
datasets of massive proportions. As a result, a great deal of
attention has been devoted lately to applying information extraction
to the blogosphere. In this tutorial, I focus on a specific
sub-problem: extracting information networks which act as summaries of
the blogosphere as a whole. These networks consist of nodes
representing entities and edges representing the relationship between
such entities. I will cover fundamental tools from NLP and network
science that allow the unsupervised extraction information networks
from social media content.
