Problems solved by technology
Although SAS models the relationship between slots by calculating a slot similarity matrix, it involves several hyperparameters that are difficult to set, and if two slots are considered to be related, only their similarity coefficient is fixed to 1 , which is obviously unrealistic
Although STAR uses multi-head attention to discover the relationship between slots, the relationship between slots calculated by the attention mechanism is equivalent to a weighted complete graph, which will generate a lot of noise (unnecessary connections) and affect model performance.
T5-DST uses the enhanced slot description to make the model better discover the relationship between slots, but it does not explicitly model the relationship between slots

The invention relates to a dialogue state tracking method and system based on knowledge enhancement and context awareness, and the method comprises the following steps: A, collecting dialogue context and dialogue state data, and constructing a dialogue training set; step B, using the training set to train a deep learning network model based on knowledge enhancement; and C, sequentially inputting dialogue data of the user and the system into the deep learning network model, and outputting a current dialogue state. The method and the system are beneficial to improving the accuracy of dialogue state tracking.
Description
technical field [0001] The invention belongs to the field of natural language processing, and in particular relates to a dialogue state tracking method and system based on knowledge enhancement and context awareness. Background technique [0002] Dialogue State Track (Dialogue State Track, DST) is an important part of the task-based dialogue task process in natural language processing, and its basic goal is to obtain the current dialogue state according to the dialogue context. Dialogue state is a summary of the user's goal from the beginning of the dialog to the current dialog, usually in the form of a combination of multiple sets of slot-value pairs, and sometimes includes information such as the domain to which the dialog belongs, user intent, etc. Dialogue state tracking refers to the process of inferring and updating the current dialog state by combining information such as dialog history, current dialog, and previous round of dialog status. With the continuous progres...
