Analyse du capitalisme social sur Twitter

Abstract : Bourdieu, a sociologist, defines social capital as : "The set of current or po- tential ressources linked to the possession of a lasting relationships network". On Twitter, the friends, followers, users mentionned and retweeted are considered as the relationships network of each user, which ressources are the chance to get relevant information, to be read, to satisfy a narcissist need, to spread information or advertisements. We observe that some Twitter users that we call social capitalists aim to maximize their follower numbers to maximize their social capital. We introduce their methods, based on mutual subscriptions and dedicated hashtags. In order to study them, we first describe a large- scale detection method based on their set of followers and followees. Then, we show with an automated Twitter account that their methods allow to gain followers and to be ret- weeted efficiently. Afterwards, we bring to light that social capitalists methods allows these users to occupy specific positions in the network allowing them a high visibility. Furthermore, these methods make these users influent according to the major tools. We thus set up a classification method to detect accurately these user and produce a new influence score.
