1. A method comprising: conducting a dialog exchange between an automated dialog system and a user, the dialog exchange including at least two dialog system prompts and two user input opportunities; and determining whether a probability threshold is exceeded that relates to a prediction that continuing the dialog exchange with the user will converge and succeed to a stage consistent with the user's intent or diverge and fail, wherein determining whether the probability threshold is exceeded is based, at least in part, training data on multiple dialog turns in a corpus of dialogs tagged for success or failure after at least two dialog prompts and two user inputs.

The method of claim 1 , wherein the probability threshold is a first threshold, the method further comprising: determining whether a probability of conducting a successful dialog with the user exceeds a second threshold, the second threshold being greater than the probability threshold, wherein if the second threshold is exceeded, further dialog is conducted with the user using a current dialog strategy.
