Target category membership analysis method, system and device and storage medium

The invention relates to a target category membership degree analysis method, system and device and a storage medium, and the method comprises the following steps: analyzing different application scene characteristics and evaluation indexes of a to-be-evaluated project, obtaining an evaluation index set and a scene characteristic set of the to-be-evaluated project, and respectively recording the evaluation index set and the scene characteristic set as a first variable set and a second variable set; performing membership analysis on the probability of occurrence of each evaluation index in the first variable set and the probability of each scene characteristic in the second variable set under different application scenes to obtain an evaluation index list under different scene characteristics; and based on the evaluation index list, determining an evaluation index subset of the to-be-evaluated item under the preset scene characteristic, and based on the evaluation index subset, obtaining an evaluation result o
