The structures of these social networking services are based on the computer networks and cloud computing, at the same time reflecting daily life relationships. Certain individuals seems to play a crucial role in the information diffusion in social networks. Such individuals seems to have some special characteristics that make them special in comparison to other individuals in social networks in terms of information diffusion. These special individuals are being generally called influentials. \nThis study addresses the emergence of the user influence in the Twitter social network service. The purpose of this study is to find out how the influ-ence of individual user is being formed when observing the information diffu-sion as well as the social network on Twitter. This study was carried out by us-ing a literature review and a case study. The data set for this study was collect-ed from Twitter in April 2013 after the Boston Marathon bombing and related with it. The data consists over eight million tweets that were created or re-tweeted by over four million different users. \nAs a result of this research it became clear that the information diffusion has its significant role to play in terms of user influence formation in Twitter. The followers are the main audience for the tweets sent by the user. When the followers are retweeting the tweets to their own followers this activity gener-ates a phenomenon called diffusion of information. If the user has a lot of fol-lowers or the followers are influentials themselves, then the diffusion of infor-mation more widely can be seen as a predictable event. If one single Twitter user can cause such chain reactions, then the user has more influence than his peers.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Miika Reinikainen (mireinik) on 2016-07-04 07:55:34.625470.
