Avoiding Chatbot Fallback Proliferation

Описание: In order to prevent an user getting stuck in a branch of the dialog, the dialog designers include in a note a true or anything_else condition. if none of the anticipated and included patterns are matched, a generic dialog is presented to the user.

The problem here is that the user is not able to digress away from the dialog branch. Hence trapping the user in the section of the dialog.
As a conversational designer and developer you need to evaluate any branch that uses this approach and ensure digression away from this point is possible. Should the user at this point enter something which is totally different from what you expect, it might match some other area of the designed dialog.

Instead of responding with a generic ambiguous message, you should leverage the work you have done as a whole and attempt to effectively put the rest of the dialog to work to address the user's utterance. 
In the final analysis if there is no regression option available, at the root-level of the dialog, an anything else node can be used when all other avenues have failed.

In this example I make use IBM Watson Assistant for illustration.
