Engineering design document index extraction method and system

Abstract

The invention provides an engineering design document index extraction method and system, and the method comprises the steps: carrying out the index extraction of an engineering design document based on a basic prompt word, and obtaining an extraction index; background knowledge fields of the basic cue words are null; evaluating the extraction indexes, and determining a failure case and a success case; performing knowledge generation on the failure case based on a meta prompt template including expert prompts to obtain background knowledge corresponding to the failure case; filling the background knowledge into a background knowledge field of the basic cue word to obtain an enhanced cue word; performing index extraction on the engineering design document based on the enhanced cue word to obtain an optimized extraction index; performing fine adjustment on the model based on the basic cue word and the optimization extraction index to obtain an optimization model; and performing index extraction on the engineering design document based on the optimization model. According to the method, dynamic injection of background knowledge is realized, and the index extraction accuracy is improved.
