Description

The following picture summarizes the bot application architecture:

Bot

• The bot was created with Dialogflow (api.ai).
• Given a user input, dialogflow identifies which action should be performed and the values of the parameters required to perform that action.
• Ex.: User says: "What's is the capital of France?". In this case, the action to be performed is "search country capital", which requires parameter "country". The value of country is "France" in this example.
• The action is fulfilled by a web service.

Web Fulfillment Service

• The Web Fulfillment Service is a Flask Application, which was implemented as a single file (app.py).
• This aplication calls a RESTful API (rest-countries) to get information about countries, and the Yahoo Weather API to get weather information.
• The application was deployed to Heroku.
