I noticed they keyword when using ODQA with python code. For the ranker part a keyword is given in order to find the correct articles to match the question, in the example from medium it is done like this:
docs = ranker([‘cerebellum’])
Now to me it seems a quite essential part of the ranker, which is why I am wondering how this keyword can be extracted when a user inputs their question/query. Is there a way that DeepPavlov automatically does this or is it optional after all?
