What is the point of ScienceWISE annotation on arXiv?
From ScienceWISE FAQ:


  Why do you need all this if there is Wikipedia?
  
  The main difference of our Ontology from most existing online resources is in a possibility to have several single-authored definitions of the same concept. Unlike Wikipedia, ScienceWISE provides a mechanism for scientific community ranking (by linking against the best definitions) and provides a peer-run quality assurance system.


You may have read that already, but unless you explain what is not clear your question is either impossible to further answer or a disguised criticism.
