The invention relates to an
engineering document index consistency proofreading method and
system based on a multi-
modal large model, and the method comprises the steps: Q1. OCR detection and recognition: carrying out the
optical character recognition and format analysis of a
source document, converting an uploaded PDF document into a processable
text message in a Markdown format, and carrying out the format discrimination of a table, a formula and a
plain text; and Q2, table and formula
processing: adopting a hierarchical
processing strategy, intelligently selecting an optimal
processing mode according to the complexity of the table, and converting
table information into a descriptive long text through a language
large model and cue words. According to the method, accurate, reliable and efficient document index checking service can be provided for a user, the quality and efficiency of professional
document processing are remarkably improved, the efficiency and quality of
knowledge graph construction are remarkably improved, a knowledge
verification system capable of being evolved continuously is established, and the method is suitable for popularization and application. And a reliable
technical support is provided for
knowledge management and professional decision-making in a
complex field.
