Nowadays,
more and more users keep up with news through information streams
coming from real-time micro-blogging activity offered by services such
as Twitter. In these sites, information is shared via a
followers/followees social network structure in which a follower will
receive all the micro-blogs from his/her followees. Recent research
efforts on understanding micro-blogging as a novel form of communication
and news spreading medium, have identified three different categories
of users in these systems: information sources, information seekers and
friends. As the social network grows in the number of registered users,
finding relevant and reliable users to receive interesting information
becomes essential. In this paper we propose a followee recommender
system based on the analysis of the content of micro-blogs to detect
users' interests and in an exploration of the topology of
follower/followee network to find candidate users for recommendation.
Experimental evaluation was conducted in order to determine the impact
of different profiling strategies based on the text analysis of
micro-blogs as well as different factors that allows the identification
of users acting as good information sources. We found that
user-generated content available in the network is a rich source of
information for profiling users and finding like-minded people. Researchers: Marcelo G. Armentano, Daniela Godoy
