Inspiration

As students, we face many challenges in our pursuit of academics. We felt that lectures can be very long and we tend to lose our focus. Thus, having a quiz available for each lecture video can help us be more attentive and learn better. We were inspired to build a project that can help ourselves and fellow students become more productive and efficient academically.

What it does

Our project firstly enables users to conveniently download videos of their choice through a chrome extension that we built. Secondly, videos can be uploaded onto our quiz generation platform to retrieve a series of questions that were generated from the input video.

How we built it

Frontend/UI - Streamlit Transcription - Amazon Transcribe Text extraction from video - Amazon Textract Question Generator - External Library using Transformers Chrome Extension - Express.JS, JavaScript Data cloud storage - Amazon S3 Machine Learning and Data processing - Amazon Sagemaker, OpenCV

Challenges we ran into

  • Integration hell and unsuccessfully deploying our Sagemaker notebook as a lambda function on AWS Lambda together with API Gateway.
  • Trying to get a higher quality of questions generated, there were a lot of incoherent questions with grammatical and spelling errors initially.
  • The overwhelming number of available AWS services and APIs and the complexity of using them successfully.

Accomplishments that we're proud of

  • We are extremely proud of building and deploying a functional AI product in less than 2 days despite our unfamiliarity with AWS and its tools.
  • We are also proud of achieving decent quality of questions generated
  • We are lastly proud of being able to use a combination of 3 fields of AI: CV, NLP and speech processing.

What we learned

  • We learnt how to navigate the AWS Sagemaker MLOPs environment
  • We learnt how to make a chrome extension with a decent utility
  • We learnt how to use and deploy AWS deep learning tools such as Textract and Amazon Transcribe
  • We learn how to integrate everything together into a user-friendly AI solution

What's next for Team AWSome - QuizzWizz - Lecture Video to Quiz Generator

  • Deploy application on a cloud server
  • Increase accuracy of transcription, text extraction and improve quality of question generated
  • Increase support for other URLs ( other than youtube .mp4 videos)
  • Increase support for other file types, e.g text documents
