Sure you can give it a try. The problem I encountered is that most journals don't have a uniform link structure, or multiple links go to the same page. Some journals have DOI's in the links, some don't. The links actually come in already expanded so you don't even have to deal with that problem. Another issue is that people often discuss studies with links from popular news, so it's hard to track those without knowing them apriori. You'll also have to deal with OAuth, which you can do but there's no easy solution for anyone except yourself. I think you'd have to create a keyword database to search for to identify links. Scott and I met with Heather and talked about the AltMetrics guy, and they were saying that's what he does. He'll search for say "sciencedirect", and terms like that. But have a go, I'd be curious to see what you get.
Cool.
ROAuth isn't so bad, at least for personal use. But I'm getting non-expanded links:
I authenticate, then run
me <- homeTimeline(n=500)
df <- twListToDF(me)
df$text[1:8]
and get all shortened links:

Hints?

Sure, you could use getURL("http://t.co/9ZEXEZDt",followlocation = TRUE) and then scrape the resulting text for a doi, or you could use the longurl api.
myURL <- URLencode("http://t.co/awT7X5Lq",reserved=T) getURL(paste("http://api.longurl.org/v2/expand?url=",myURL,"&all-redirects=1",sep=""))
The problem I've had with that is that sometimes it fails to expand links that work in my browser, not sure why.
It would be great to pull my morning twitterstream into R (from
homeTimeline()
), grab all the links, and see which ones correspond to DOIs (ideally also identify links directly to journal websites). Then I could see what papers were being most discussed in my circles, and possibly what people were saying about them too.I could take a whack at this if you like. Know any good way to expand shortened links or identify if they correspond to a pub? The totalimpact folks must have that figured out, so this should be pretty straight forward?
