Pierre Lindenbaum has created a tool called PubMed2Wikipedia:
First, the user select a set of articles about a given subject from pubmed, the software then download, prepare and format the data for a new wikipedia page. For example it creates the ‘references’ part and suggest the Categories: from the Mesh terms. I’ve also included a dictionary which recognize some regex patterns to help create a wikipedia internal link.
