Re: How to train the model using user clicks when use ltr(learning to rank) module?

Hi,

NLP4L[1] has not only Learning-to-Rank module but also a module which calculates
click model and converts it into pointwise annotation data.

NLP4L has a comprehensive manual[2], but you may want to read "Click Log Analysis"
section[3] first to see if it suits your requirements.

Hope this helps. Thanks!

Koji
