Covid-Chatbot

The chatbot should answer the questions of the user to topics concerning Covid-19.

The bot will display r-index and similar up-to-date statistics as well as information on how to prevent and cope with covid. A focus of the bot is on creating statistics as plots. To achieve this the text input is interpreted and reasonable x and y-axis labels are applied. The data for the plot is received through APIs from credible sources like the Robert Koch Institute.

File structure

The current development state is in the rasa_chatbot_v2 folder. The docker_rasa_chatbot was our attempt to dockerize the application. However, this was not successfull. The Chatbot-Widget folder contains the files for the frontend of the chatbot.
