Achieving and maintaining important roles in social media
作者：
Highlights：
• The paper deals with a significant problem how the user in social media should behave to obtain or maintain an influential position in the group.
• The evolution of user roles in various social media having significantly different characteristics follows similar patterns - in the two portals considered (Huffington Post and Salon24) sets of frequent temporal transitions between roles performed by users overlap significantly.
• Users in social media more often maintain roles that they play in groups in time than change these roles. If the role performed by the user in the group changes, it more often results from the decrease in the user’s importance than its growth.
• The size of the group affects the percentage of users with an influential role within them, in smaller groups it is easier to get an influential role because of the more direct relationships between all members of such a group.
