Using NLP to generate Quizzes

Submitted Jul 30, 2019

The Problem

  • Quizzes/Questions are required by students for self-evaluation and by teachers to test students.
  • However, quiz creation currently requires manual effort and understanding of the topic which making the process difficult to adapt and scale.
  • Multiple-Choice Questions have been proved to evaluate student’s understanding of concepts and can exhibit broad ranges of difficulty and therefore, test different levels of understanding.
  • However, MCQs require challenging options which can be cumbersome to pick.

The Solution

  • Using NLP to generate Multiple-Choice Questions from plain-text
    • Statistically determines best entities to blank
    • Generate semantically similar options based on context and corpus
    • Better than subjective questions MC questions tests
  • A user-interface to generate quizzes
    • From any document
    • On any topic in any genre (Educational or Recreational)
    • From any paragraph
