The invention relates to a large
language model-based job matching scene query understanding method. The method comprises the following steps of: receiving a job name, a
job description and job requirement information input by a user; performing
noise filtering and coding normalization
processing on the input post information to generate a standardized text; geography and organization entities are extracted through a
named entity recognition model, cue words are finely adjusted through a large
language model, structural constraint conditions are formed by technical recognition educational background, working years and ages, and a condition analysis template is dynamically generated. And finally, through a large
language model, verifying the accuracy of the keyword items, and allocating weight coefficients for the lexical items. Therefore, the efficiency is remarkably improved. Through automatic semantic analysis of a large language model, manual deep intervention of professional
knowledge learning of posts is not needed, and core information such as post responsibilities and skill requirements can be rapidly extracted and converted into semantic retrieval features.
