These kinds of intimate social networks with the closest, most
meaningful ties, such as between close friends, family, relatives
and even close colleagues, are characterized by high frequency of
interaction, but also by a great need to feel connected, to be in
touch [14], and a need for sharing detailed activity and context
information [11]. However, scarcely any of the online social
networking applications1
[15]
support users adequately in staying
connected with this core group of people . To address this
problem, we have developed Friendlee, an application that
analyzes the user’s call and messaging activity to identify the
user’s closest social contacts. Friendlee enhances the mobile
phone, providing the user with an ambient awareness of her
intimate network.
