In this paper, we present a study of <em>group split</em> in <em>Meetup</em>, where a major fraction of members leave the existing group together and join a newly formed group. We identify pivotal group members, called <em>splitters</em>, playing key roles in <em>group split</em> by influencing the existing members to leave the group. We provide an in-depth analysis of the empirical data to reveal key motivating factors leading to a <em>group split</em> and its subsequent impact. Finally, we develop a prediction model for early detection of <em>splitters</em>, as well as the group members likely to be influenced by the <em>splitter</em> to leave the group.</p> ER -
