Abstract
A method, a structure, and a computer system for OOD sentence detection in dialogue systems. The exemplary embodiments may include receiving, for a domain corresponding to a particular topic, one or more on-topic text inputs and one or more off-topic text inputs. The exemplary embodiments may further include encoding the one or more on-topic text inputs and the one or more off-topic text inputs into a latent space, as well as decoding the one or more on-topic text inputs and the one or more off-topic text inputs from the latent space. The exemplary embodiments may additionally include minimizing a reconstruction error between the encoded one or more on-topic text inputs and the decoded one or more on-topic text inputs, and maximizing a reconstruction error between the encoded one or more off-topic text inputs and the decoded one or more off-topic text inputs.
