🎯 A chatbot to book flights

The aim of this project is to prototype a 1st version of a chatbot, which will help colleagues of the FlyMe company to book a vacation.

The MVP (Minimum Viable Product) should help us to identify the "BookFlight" intent and return the 5 main entities which constitutes flight' details:

• origin city;
• destination city;
• departure date;
• return date;
• bugdet.

Expected output: the Bot should be able to reformulate the flight's details, ask confirmation (yes/no) from the user, then, if correct, end conversation with a booking message.

🗂️ Dataset

Microsoft Frames Dataset

The dialogues were built with 2 humans' talk via a chat interface, one was playing the role of the user and the other one was playing the role of the conversational agent (a database of 250+ packages was available to compose of a hotel and round-trip flights).

The dialogues are more complex than what we need for the MVP, thus, it's very good basis for the next steps of the project.
