Q:

how to jump between dialog without confusion on watson assistant(conversation)?

There're 3 main nodes in our watson conversation(assistant) dialog, we'd like to ask question between each nodes and each of them have a long child nodes, how can we keep the previous answer while we jump to ask another question ?for example, A qustion like: I'd like to book a flight, Answer: what'd date is your flight? Then Ask: My car is out of oder, Answer would be: please get to a repair store, now I will keep answering that flight date, a complex dialog diagram as the attached, any advice would be appreciated... another example as follows: ask a question on node1(not finished yet), ask another question on node2(finished), then keep answering question on node1 

A:

You can gather multiple pieces of information from a user within the same node as an alternative to create child nodes usings SLOTS. Slots collect information at the users' pace. Details the user provides upfront are saved, and the service asks only for the details they do not.
