Final Report for GSoC'18 (Systers, PC-Prep-Kit)


An app that teaches about various aspects of Malaria. This would be achieved using Gamification and ChatBot. Teaches about,

  • What is Malaria?
  • How it is caused?
  • How to prevent it?
  • How to treat it?

Tech Stack

  • Angular 6
  • NodeJS
  • MySQL + Sequelize
  • Rasa_Core ( + Tensorflow)
  • Karma and Mocha (for testing)

Future Development

  • Current bot accuracy is 70%, can be increased more.
  • More scenarios can be added to Bot conversation.
  • Adding location feature in the application and providing content based on the location.
  • We may shift from MySQL to NoSQL.
  • Mocha and Karma test coverage can be increased.
  • Automated lint checking for GitHub commits.
  • Implementing Object Oriented patterns in current backend code.
  • Add more games!
  • Reactive Design patterns using NgRx


  • Malaria, a life threatening disease.
  • In 2016, 216 million cases in 91 countries. (Reference, WHO)
  • Nearly half of world population at risk.
  • Early diagnosis helps in preventing deaths.
  • Some communities in the world are still unaware of it.
