Finding the most important questions from a questionary-> results
If selecting the most important and relative questions is the question and you choose the option:

option 1.) find the closest document to each answer(30 docs) and after the documents are validated relative or not. You will have the results of each person's evaluation (Xpersons x 30 scores). Now order the questions in descending order from most scored question to less scored one.

option 2.) Summing up all the answers and finding 20 docs. After the validation of relativeness by the persons, it is not possible to find the important features(questions) because they are summed up and the information is already lost. From this result you could only find which person validates closer to your model among all, which is not the aim of the work.
