== Demand of Deletion Withdrawal == 

 Dear Editor: 
 Please check the deleted item "concept cloud" again.The main reference resources of the article are two research papers, both published in peer-reviewed sources. "StYLiD: Social Information Sharing with Free Creation of Structured Linked Data" is published in Proceedings of the Social Web and Knowledge Management Workshop(SWKM 2008), pp. 33–40, Beijing, China (2008), Located at the 17th World Wide Web Conference (WWW2008), whose accepted papers are all peer-reviewed by at least three reviewers from an International Program Committee. This information is available on their website: http://www2008.org/CFP/index.html 

 "The Design and Realization of Information Retrieval System Based on Concept Cloud and ontology" has been accepted by Journal of the China Society for Scientific and Technical Information, one of China's most prestigious peer-reviewed journal in this field.  

 According to the guidelines, "If the material has been published in reputable peer-reviewed sources or by well-regarded academic presses, generally it has been at least preliminarily vetted by one or more other scholars." the references are reliable sources, so my article could not be seen as non-notable. I hope this will help on the withdrawal of the deletion. Thank you.
