Which model of transformers to use if I want to do multiclassification of a pair of sentences containing a questionair
I have a corpus of sentences and each sentence is assigned to a code which look like a  question. My aim is to classify the pair as a unit.Given the sentence, sentence_question , the model give a classification for example A . I have three classes. Note that the question are fixed  and are 21 in total.For exemple : je suis bien; quel est son statut ?  === class A. I want the sentenceQ to be an element to help the classifier  choose the overall class of the whole pair. Is it possible to do it with BERT sentence similarity ? or is not the good model ?Should I give the pair as a single sentence to BERT or not ?
