  In this paper, we propose an ontology schema towards semantification
provision of Twitter social analytics. The ontology is deployed over a publicly
available service that measures how influential a Twitter account is, by
combining its social activity and interaction over Twittersphere. Apart from
influential quantity and quality measures, the service provides a SPARQL
endpoint where users can perform advance semantic queries through the RDFized
Twitter entities (mentions, replies, hashtags, photos, URLs) over the semantic
graph.
