Influence Tracker

[Influence Tracker] (http://www.influencetracker.com) is a service for calculating the importance and influence of an account in Twitter. Moreover an [ontology] (http://www.influencetracker.com/ontology#) is proposed towards the semantification of the Twitter accounts, the disseminated information and the respective Twitter entities (mentions, replies, hashtags, photos, and URLs) as Linked Data.
