Social media sites have become very popular within large enterprises. Still, employees are experiencing difficulties in engaging efficiently. In this paper, we present a study of a personalized action recommendation system in an enterprise social network. Following a previous study on how to raise one's social eminence in the enterprise and a set of interviews, we built an innovative recommendation system which provides employees with concrete personalized recommendations on how and where to engage. Differently from other systems, it presents recommendations in context of limiting social network behavioral patterns. The recommendations' goal is to assist employees in growing out of these patterns. The paper presents the interview findings, the innovative recommendation system and results of a wide survey investigating the effectiveness of such a system.
