I was trying out various projects available for question generation on GitHub namely NQG,question-generation and a lot of others but I don't see good results form them either they have very bad question formation or the questions generated are off-topic most of the times, Where I found one project that actually generates good questions

bloomsburyai/question-generation

It basically accepts a context(paragraph) and an answer to generate the question and I am trying to validate the questions generated by passing the generated question along with the paragraph to allenNLP

Answer generation for a question

And then I am trying to make sure the generated answers are correct for the questions generated with calculating the sentence embedding for both the answers(AllenNLP and PotentialAnswer) using Universal Sentence Encoder and a cosine distance to get how similar the answers match and the filtering question that has least cosine distance.

Wanted to know if this is the best approach or Is there a state of the art implementation for question generation? Please suggest

  • $\begingroup$ The way you are doing will suffice if you are going to feed it to a neural network for training. But if you want to display it to user then it may not be that appealing. What is your actual purpose? $\endgroup$ – Sandeep B Aug 3 at 18:03
  • $\begingroup$ @SandeepB my end purpose is to display it to the user. $\endgroup$ – Sundeep Pidugu Aug 6 at 7:14

It seems that state of art methods use neural encoder-decoder models [1]

[1] Neural Question Generation from Text: A Preliminary Study : https://arxiv.org/pdf/1704.01792.pdf

There is an open source implementation of the paper written with Pytorch on github : https://github.com/magic282/NQG

  • $\begingroup$ Is there any open-source implementation of the same? $\endgroup$ – Sundeep Pidugu Jul 29 at 9:14
  • $\begingroup$ Yes, I edited my post $\endgroup$ – Alexis Pister Jul 29 at 9:56

Keep an eye out on https://github.com/sebastianruder/NLP-progress/blob/master/english/question_answering.md which is regularly updated, the main repository https://github.com/sebastianruder/NLP-progress also shows the state-of-the-art on other tasks

  • $\begingroup$ Thanks but I see all of them are somehow related to question-answer generation but nothing specific to question generation as such but will be watching the repo for changes. $\endgroup$ – Sundeep Pidugu Aug 6 at 7:15
  • $\begingroup$ @SundeepPidugu you could try running some of the models in reverse perhaps? Swapping the input and output, don't know if that's valid but both seem like seq2seq tasks $\endgroup$ – JoelKuiper Aug 6 at 8:30
