There have already been previous study on influence in different domains, for example in the domain of marketing. In this paper, the authors focused their study on the social media Twitter. They wanted to know what kind of influence twitter users can have on each other.
3 Measures of influence:
In their research they make a contrast between 3 measures of influence. The first one is the number of followers people have on twitter (called indegree). Their conclusion is that this measure shows the popularity of the user, but it doesn't show the influence on other users. The second one is the number of retweets a user has, here they saw that the content value of a tweet has an important role . The last one is the number of mentions a user gets, this depends of the value of a name.
Connection between indegree, retweets and mentions:
Next, they studied the effect of the 3 measures on each other. They found that there is a link between the number of retweets and mentions. Furthermore they concluded that indegree has no relation with the other two measures. The last item they investigated was if the influence of a user changed over time. The result of their investigation is that users have to do efforts to maintain their influence.
