The invention discloses a user
question answer output method for a hot rolling
production line intelligent operation and maintenance online question-answering
system. The method comprises the following steps: obtaining operation and maintenance documents in the iron and steel industry, and screening to generate expert question-answering pairs; carrying out vectorization
processing on the expert question-answer pairs and then storing the expert question-answer pairs in a vector
database; performing vectorization
processing on professional documents of the iron and steel industry and fault maintenance and disposal reports of a
production line over the years, and loading the vectorized documents and the fault maintenance and disposal reports into a vector
database; when a user asks a question, vectorizing the question of the user, comparing the question of the user with an expert question-answer pair pre-stored in a vector
database, and directly outputting an answer of the expert question-answer pair as an answer of the question of the user when the similarity is high; if the similarity is low, inputting the user question and the similar expert question and answer pairs and
paragraph texts in the vector database into a large
language model, and summarizing and outputting a congruent answer of the user question by the large
language model according to the user question and the similar expert question and answer pairs and
paragraph texts. According to the method, the accuracy of outputting answers for the user questions is greatly improved.
