Here is an example what it did with the initial words and accepting all further suggestions:
Jeff Dalton is a researcher at the University of California at Berkeley...
An amusing example. I'm actually quite surprised it autocompleted "researcher" correctly. However, Scribe got the university wrong. It looks like UC Berkeley wins the web popularity contest.
Overall, Scribe appears to be a straightforward application of web n-gram language models covered in an AJAX interface. Some of its mistakes demonstrate the drawbacks of not utilizing long range word dependencies and topical context. Still, an interesting step towards more autocompletion. I think there may be interesting opportunities to improve effectiveness by leveraging custom language models built from my other documents and web history.
