Social Influence Measurement

Can Social Influence Measurement systems  help  identify who influences whom internally or externally / inside or outside the organization leveraging the big data from the Social chatter that goes on in Social media space ? For example - If I retweet you or repost your status update , does Social Pulse infer that You influence me ? But what if same content gets shared multiple times on a social platform without attribution to the person who originally posted it or shared it ? Would Social Pulse identify who discovered and  shared the content first and determine influence ? Or Is Influence as a measure independent of who shares what / whose content & relies totally on engagement levels generated as a result of activities on Social platforms ? Social Capital and Social Influence -  are mutually exclusive ? Not yet , perhaps.Will Klout and Kred such companies gain prominence as Social Influence Analytics companies ?
