How we developed a chatbot to fight against COVID-19?

I remember the night when a nationwide lockdown was declared. We were all sitting around bored, thinking, "Something has to be done with the excessive amount of data flowing around in GitHub." People were creating numerous APIs, web sites and mobile apps to provide information about the disease.

πŸ€• Problem

People had so many questions, but the answers are usually very scattered (different websites and apps). Finding out the right information is hard and it takes a lot of time. To judge the reliability of that information is important as well.

πŸ’‘ Solution

We concluded that we needed something which was:

  • πŸ€— Trustworthy
  • ⚑ Quickly accessible
  • πŸ—£οΈ Interactive

⌨️ Implementation

We finally decided to make something that combined the three factors stated above. A Chatbot was the answer.

We started looking for the data sources which provide maximum accuracy and reliability. We found CSSEGISandData/COVID-19 a data repository operated by Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE). It as the most accurate data on the internet. Also, it's the primary source of all other APIs available out there. We also found some supercool APIs, so we integrated all of them into one.

🌟 Features

Fast forward 4-5 days, we've created a Telegram chatbot, named @CoDoc19Bot, with the following features:

1) πŸ€– QA
You can ask your questions right away. With the support of NLP (Natural Language Processing), it will answer all your questions.

2) πŸ₯Ό Corona Test
To check the likelihood of having COVID-19.

3) πŸ€” Quiz
Are you taking the correct protective measures against COVID-19? Find out.

4) πŸ“ˆ Statistics
To get global COVID-19 statistics with charts.

πŸ“£ Publishing

On April 5th, we released the first version through ProductHunt. People started to use it. After 6 hours, we had around ~600 active users with ~3000 requests processed.

πŸ’£ What went wrong?

1) After the release, one of the external APIs changed their API structure without any notice πŸ˜“. Luckily, we came to know the error and fixed it in a couple of minutes.

2) We couldn't test it with all the countries. So, in the CSSEGISandData dataset, South Korea was labeled as Korea, South and we've been using simple string explode function to parse the CSV πŸ™„, as a result 🀷, it broke. We timely fixed it with a good CSV parsing algorithm. πŸ˜€

πŸ‘† What we learned?

  • Do not deploy anything without thorough testing πŸ˜‹
  • If you're using any external API, try to monitor it using a program.
