TECHNIQUES FOR UPDATING A PARTIAL DIALOG STATE

摘要

Embodiments provide for tracking a partial dialog state as part of managing a dialog state space, but the embodiments are not so limited. A method of an embodiment jointly models partial state update and named entity recognition using a sequence-based classification or other model, wherein recognition of named entities and a partial state update can be performed in a single processing stage at runtime to generate a distribution over partial dialog states. A system of an embodiment is configured to generate a distribution over partial dialog states at runtime in part using a sequence classification decoding or other algorithm to generate one or more partial dialog state hypothesis and/or a confidence score or measure associated with each hypothesis. Other embodiments are included.

1. A system configured to:
receive user input at a first turn; generate a semantic representation based on the user input at the first turn; generate a partial dialog state based in part on the semantic representation associated with the first turn; receive user input at a second turn; generate the semantic representation based on the user input at the second turn; and update the partial dialog state for the second turn using a discriminative model using the semantic representation associated with the first turn and the second turn.
