    Abstract

    Recommendation is usually reduced to a prediction problem over the function
    $r(u_a, e_i)$ that returns the expected rating of element $e_i$ for user $u_a$.
    In the IPTV domain, we deal with an environment where the definitions of all
    the parameters involved in this function (i.e., user profiles, feedback ratings
    and elements) are controversial.

    Abstract

    The present work investigates the structural and dynamical properties of
    aNobii\footnote{this http URL}, a social bookmarking system designed
    for readers and book lovers. Users of aNobii provide information about their
    library, reading interests and geographical location, and they can establish
    typed social links to other users. Here, we perform an in-depth analysis of the
    system's social network and its interplay with users' profiles.
