Intelligent bidding document evaluation method and system based on quantification rule

The invention relates to the technical field of bidding document evaluation, in particular to an intelligent bidding document evaluation method and system based on a quantification rule, and aims to improve the efficiency, accuracy and fairness of bidding document evaluation and reduce the influence of human subjective factors. The method comprises the steps of presetting an evaluation index set of a bidding file according to bidding item content; bidding document electronic information of all the units participating in bidding is acquired; according to the evaluation index set, key factor extraction is carried out on the electronic information of each bidding document, and a key factor feature set of the bidding document is obtained; constructing an essential factor feature conversion model based on a quantization rule, and preprocessing each key factor feature set by using the essential factor feature conversion model to obtain a key factor feature vector; and based on a multiple linear regression technolog
