⚙️ Requirements

• Python 3.6.*, 3.7.* or 3.8.* (for this project Python 3.7.10 has been used)
• Rasa
• Rasa X (optional)

🔧 How to use

• Clone the repository https://github.com/sebastianochiari/LUS-final-project
• Install all the dependencies listed above
• Train the model

rasa train

This will store a zipped model file in the models/ folder and set the latest trained model as active.

💻 Local

To chat with the bot on your local machine, start two servers on two different terminals, running the following two commands

rasa shell
rasa run actions

🔮 Alexa

To chat with the bot using the ASK infrastructure, do the following instructions:

• create an Alexa Skill on Amazon Developer
• replace the JSON file in the JSON Editor with the alexa_schema.json you can find in the repository
• launch the following commands in three separate terminal shells

rasa run actions
rasa run -m models --endpoints endpoints.yml
ngrok http 5005

• update the endpoint on the Alexa Developer Console by selecting HTTPS, "My development endpoint is a subdomain of a domain that has a wildcard certificate from a certificate authority" as SSL certificate and copying the ngrok url concatenated with webhooks/alexa_assistant/webhook

🔊 Actions

The following list contains all the possible questions the bot is able to intend and respond:

• ask what the bot is able to do

what are you capable of?

• ask for an F1 joke (retrived from https://upjoke.com/f1-jokes)

make me laugh

• search the F1 championship winner given the year

who won the 2020 F1 championship?

• search driver info given its name

what can you tell me about Carlos Sainz?

• search the drivers by constructor name and the year (optional, if nothing is specified it tries to look within the current year) (working with forms, maybe not necessary)

2014 Ferrari drivers

• search a race result (two options, ranking returns the podium of the race, driver returns its race outcome)

I want to know the race results for the British Grand Prix in 2008

• search the next race in calendar

when will be the next race?
