7 more Connotea/CiteULike tags to check for connections to PubMed & MeSH. 

Here is the current breakdown:

# of tags in Connotea that match a MeSH term for the citation 39/161 or 24%                                

# of tags in CiteULike that match a MeSH term for the citation 44/170 or 25+%

# of  citations in Connotea that are also found PubMed 81/161 or 50+%

#of citations in CiteULike that are also found in PubMed 105/170 or 61+%

It is looking more & more that tagging in Connotea/CiteULike does not have any relationship to MeSH terms; the taggers are using PubMed to find their information.  (As an aside, many of these citations are for articles that  freely available on PubMed.  That is not part of this research but would make for another paper.  Are social taggers using more free materials?  What are the origins of the taggers?)
