Domain element recognition model training method and device and electronic equipment

Abstract

The invention provides a domain element recognition model training method and device and electronic equipment, and belongs to the technical field of natural language processing. The method comprises the following steps: labeling a training data set by utilizing a preset domain dictionary and a preset regular expression so as to generate first reference entity labeling information corresponding toeach piece of training data in the training data set; performing identification processing on the training data set by using a preset element identification model to determine prediction entity labeling information corresponding to each piece of training data; and updating a preset element identification model according to the difference between the prediction entity annotation information corresponding to each piece of training data and the first reference entity annotation information. Therefore, through the domain element recognition model training method, the recognition effect of the element recognition model is effectively improved, the universality is good, the element recognition efficiency is improved, and the labeling cost is greatly reduced.

Problems solved by technology

[0005] The field element recognition model training method, device and electronic equipment proposed in this application are used to solve the element recognition method based on rule matching in related technologies. Since the establishment of the rule system requires a lot of energy, and can only recognize the existing rules covered elements, so not only the generalization ability is weak, but also the problem of high labor cost
