I have a software in which I use Weka software to train a model (classifier) just once (without any modification) and save the model somewhere. Then, our customer gives a document to the program and gets the result back based on evaluating the saved model on the given document.
What our customer does is just sending a request to the server through the website and getting the results back. Does it mean that we are distributing the code according to GPL?
If I don't want to make our code under GPL license, can't I use Weka?
