The power industry needs to combine the specific standards specified in the industry standard specifications to accurately evaluate the quality of the equipment. Through the text differentiation model based on the retrieval and reordering model, this paper establishes standardization techniques for automation, informationization, and intelligent differentiation, which effectively solves the time-consuming and labor-intensive problems of current equipment quality assessment, and improves the accuracy of text difference retrieval . The article mainly focuses on the standardization and differentiation techniques of automation, informationization, and intelligence. Through the information retrieval model based on the retrieval reordering model, the retrieval comparison of different standard texts in the same field is established, and different documents retrieved have different requirements for the same technology. Different content and early warning tips. The innovation point in this paper is to further improve the accuracy on the basis of retaining the recall ability of the traditional differential retrieval and recall model by taking advantage of the high accuracy of retrieval reordering. The model was systematically and robustly cross-validated on the actual technical standards documents of the power industry, and it was verified that the proposed model has excellent results and the model has good practicability. It can be widely used in power equipment quality evaluation, supplier evaluation standard retrieval and other fields.
