Abstract
Techniques for chatbot utterance routing in a provider network include jointly training a service classifier and a plurality of auxiliary classifiers based on a mixed service set of labeled chatbot utterance training examples to yield a trained service classifier. When a particular chatbot user utterance is received, the trained service classifier can be used to determine if the utterance is in-scope or out-of-scope, and if in-scope, to determine which service of a set of services in the provider network to which to route the utterance for further processing. By jointly training the service classifier with the auxiliary classifiers, the accuracy of the in-scope/out-of-scope determination by the trained service classifier is improved as well as its accuracy in routing the utterance to the appropriate service for processing the utterance as intended by the user.
