Creating the NEVA Settings Business Entity
The NEVA bot is created using the NEVA Settings Business Entity.
NEVA can work in simple or advanced mode:
Simple mode: Amazon Lex handles the entire conversation until the intent is established and then returns either Fulfilled or Failed.
Advanced mode: The NEVA developer handles each and every step in the conversation. Amazon Lex returns the state of the user interaction. See Using NEVA in Advanced Mode. Amazon Lex returns the state of the user interaction in the form of a NEVA Response Received event. See Understanding NEVA Events.
