On the user's browser there's a javascript call which goes out and says: “How should things be ordered?” You put that javascript call on the top of your web page. What's happening in the background is that the the structure on the web page is getting boiled down to features which are getting turned into an example which is fed into Vowpal Wabbit once joined with a click or not signal. Essentially every individual event is treated in an experiment which has a duration of 10 minutes. If a click comes in that 10 minutes it will be joined in the example and that will be something positive saying oh yes it's good, or if it's not there then it'll be negative saying it's bad.

We have probably half a dozen different framings that we've worked on that are in different levels of development in terms of making deployable applications. The first plan is getting the kind of personalization up because we have big success stories there. The second plan is enabling things so that data scientists / Dev can do their own framings and do their own fun stuff. That's happening over the summer and the documentation for how to do your own features for example will be there by the time you run QCon. The third plan is more about trying to fully capture some framings as we develop them.
