I was talking to a marine biologist friend who was saying that he really wished Google Alerts would cover Google Scholar results also. Right now alerts only cover news, blogs, web, video or groups content.
It was a chance to play with Yahoo Pipes, and potentially applicable for a project at work, so I threw this pipe together:
You can search for a keyword since a specified year, and you should get the title, link and the source of articles. You can sign up for email alerts for changes to the results as well, so essentially doing the same thing that Google Alerts would do. This will work until Google messes with the <span> tags on the page…the pipe is thrown together with a bunch of regular expression filtering.
update: Yahoo seems to drop the search terms when you try to sign up for the email alerts.
update 2: Google disallowed scraping of the scholar results page, so this pipe no longer works.
