Can I use this library for the ranking task?

[TheEdoardo93]

Hi, I'm a computer science student based in Milan.
I want to know if I can use this library (especially, with the Python interface/wrapper) for the ranking task. I want to learn a ranking function in Learning to Rank style.
It is possible?

Thanks for the answer!

Thanks. 1) I see that this library is written in C/C++. Is there any available Python wrapper/binding? 2) So, this library doesn't permit to perform learning to rank task? Thanks for your answer Edoardo Casiraghi [email protected]

We don't but it should be easy to modify liblinear's python setting here.. TheEdoardo93 writes: Thanks. I see that this library is written in C/C++. Is there any available Python wrapper/binding?

Sorry, what do you mean by "modify liblinear's python setting here"?

1. Do I have to modify only the settings (so only the parameters to pass to the training model) or change the code of this library, i.e., implement a wrapper for ranking task?
2. The first step of generating the pair-wise combination of training examples, i.e., transforms a n-class ranking problem into a two-class classification problem, who do this step? This library or a code written by me?
