Hi Mike,

There’s a link to a conference paper on Sifter, but admittedly the automatic scraping isn’t good enough for general use. So Sifter remains only a research prototype. I’m more of an HCI guy than a machine learning guy, so I focused more on the interactions in Sifter than the actual screen scraping 🙂

Regarding Timequilt, I did that at Microsoft Research and they have the code … It’s from 2004, so a bit old. You might want to look at PicLens (https://addons.mozilla.org/en-US/firefox/addon/5579) or something newer.

Cheers,

David
