HS code matching method and system based on intelligent analysis and recognition, HS code display method and system based on intelligent analysis and recognition and storage medium

Abstract

The invention relates to the technical field of form generation, and discloses an HS code matching method and system based on intelligent analysis and recognition, an HS code display method and systembased on intelligent analysis and recognition and a storage medium, and the method comprises the steps: obtaining a to-be-judged object; correcting an imaging problem; detecting a text in the to-be-judged object; recognizing the text content; extracting required fields and/or elements from the text recognition result to generate to-be-judged object description information; according to the obtained description information of the to-be-judged object and pre-trained graph data, judging the category of the to-be-judged object, and performing entity linking with the graph data; training the pre-trained atlas data in combination with a semantic library to generate a model according to provided HS coded document data, and carrying out continuous learning and optimization by external data feedback and an AI algorithm. The intelligent knowledge search engine capable of meeting the customs declaration pre-classification service field is built to meet the requirement for quickly obtaining knowledge, and can accurately correspond to various columns in combination with character recognition.

Description

Technical field[0001]This application relates to the technical field of form generation, in particular to HS code matching and display methods, systems and storage media based on intelligent analysis and recognition.Background technique[0002]HS code (Harmoniszation System Code, International Commodity Harmonized Classification Code) is a harmonized coding system formulated by the International Customs Council, which is a unified standard for quantitative management of the tax rates imposed or refundable on entry and exit of various products.[0003]There are many HS code categories, including 22 major categories, 96 main category chapters, and a total of tens of thousands of sub-categories. The available information related to HS code classification during customs clearance is mainly commodity names and commodity specifications (that is, declaration elements), and the total number of ten-digit codes is tens of thousands. Therefore, when users have knowledge needs, the first considerat...

Problems solved by technology

At present, the knowledge in the field of customs declaration and pre-classification is relatively mature, but in terms of knowledge representation, organization, and management, it still adopts a relatively backward electronic document method. The connection between knowledge is not well established, and there is an information island problem among knowledge.

At the same time, there are certain similarities in many classification systems in the pre-classification process. The same question may have
