The invention provides a conversation state tracking method and device, electronic equipment and a storage medium. The method comprises the steps of encoding historical dialogue data through a dialogue historical encoder in a pre-constructed dialogue state tracking model to obtain word representation data after encoding of the historical dialogue data, and encoding each dialogue statement in the historical dialogue data to obtain first sentence representation data after encoding of the historical dialogue data; according to the first sentence representation data, the to-be-tracked field and the to-be-tracked slot in each field, constructing a relationship between slots and a relationship between the slot and historical dialogue data through a graph neural network model in a dialogue statetracking model, and obtaining encoded second sentence representation data and slot representation data; and according to the second sentence representation data, the slot representation data and the word representation data, generating a decoder through a slot value in a dialogue state tracking model to obtain a dialogue state of the historical dialogue data. Accuracy and expansibility of the DSTare improved.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a dialogue state tracking method, device, electronic equipment and storage medium. Background technique [0002] Dialogue State Tracker (DST) is the core component of task-oriented dialogue system. The purpose of DST is to extract the goals / intentions expressed by the user in the dialogue and encode them into a compact representation of the dialogue state, i.e. a set of slots and their corresponding values. Moreover, with the increase of skills or domains in intelligent assistants, multi-domain dialogue state tracking has attracted more and more attention of researchers. Multi-domain dialogue state tracking brings new challenges to dialogue state tracking. [0003] For multi-domain dialogue state tracking, the existing solutions mainly include the following: 1. The method based on picklist (selection list), which encodes the dialogue history and splices it with a specific ...
