The application discloses a
patent literature intelligent classification method and
system based on semantic understanding, acquires
patent literature data and classification
system configuration parameters, recognizes high-density semantic areas through
text segmentation and
information density analysis, and constructs a classification index
library; adopts a pre-training model to perform vectorization coding to form a
semantic vector space, identifies ambiguous feature points through bidirectional semantic detection to form a theme clustering space; implements
label matching analysis on the theme clustering space, and performs priority sorting and disambiguation
processing to establish a semantic
classification rule library; decomposes a classification matching strategy into core feature and auxiliary
feature matching sequences, extracts field attributes of a candidate classification set, and implements weight proportioning to determine classification attribution parameters; extracts
semantic mapping rules in combination with source
language identification, and realizes cross-language retrieval through
semantic alignment, thereby realizing accurate understanding of patent technology
semantics and supporting multilingual retrieval.
