The invention relates to the technical field of text
label application management, and provides a coding and application method and
system constructed based on a rule file and a corpus, and the method comprises the steps: carrying out the file coding of the rule file; performing chapter and section term coding on chapter and section terms in the rule file; constructing a corpus unit; file codes, chapter and clause codes and corpus units are associated and combined to form a traceable code combination, the traceable code combination is applied to standardized marking of business file key information, standard reference
traceability is formed through coding, and a business corpus can be formed by combining
business practice and generalization mapping to improve the application effect. According to the method, reverse tracing of original rule files, clause positions and
morpheme semantics is realized, and forward retrieval can be carried out by utilizing texts which are matched with conditions through codes. According to the method, semantic disambiguation and accurate
traceability of the rule text are realized through a multi-level coding
system, meanwhile, the generalization understanding capability of an AI technology is compatible, and the accuracy of text marking is improved.
