I think this discussion highlights the need for more structured document
formats on the internet so you can separete out mirrored or copied
text( see for example all the ad supported sites that simply copy wikipedia
content).
I've sometimes done things like this with pubmed
citations but they provide something called "eutils" api
http://eutils.ncbi.nlm.nih.gov/
so you don't need to scrape html or other human readable content.
It is then easy to plot paper or author count as function of year
for some key word criteria and it can be interesting to see how
fads come and go.
You see a lot of questions here on " how do I use R to scrape html"
and it is a big problem in doing many kinds of analysis. Yahoo
is doing a nice service by making downloads of histoical data available
but this is not common, even places like census often only offer
Excel format downloads ( while this is fine for R users, csv files would be just
as good and reach a wider audience )
and some places do require you to make complicated POST or other request types.
