Difficult to be performed on a large scale in the past, but with the recent boom in social media, written opinions are easier to attain, allowing this interesting problem to be explored. In this work, we have proposed a new approach for influencers detection. For this purpose, we have investigated on information cascade. The proposed approach is promising since it leverages web intelligence to integrate semantics to the problem of influencers detection in social networks.enInformation Epicenters: Detection Based : content of interactionThesis
