Abstract: Techniques for influence scoring for social media authors are described. Generally, an influence score indicates a relative level of influence that a particular social media author has in a social media environment, such as compared to other social media authors. According to various embodiments, events correlated to social media authors on different social media platforms are used to determine influence scores for the authors. To enable events that are correlated to social media authors to be quantified for purposes of determining influence, various metrics are defined that correspond to the events. An influence score for a social media author can be calculated using values for a group of metrics associated with the author.
