The invention discloses a customer portrait matching and positioning method and
system, and particularly relates to the technical field of portrait matching and positioning, and the method comprises the steps: carrying out the cleaning and time correction of multi-source behavior data under a unified time base, and constructing a behavior
time sequence and a
label time sequence; on this basis, identifying a tag high-intensity activation interval, and forming a multi-time scale portrait structure composed of a long-term structural portrait, a life cycle stage portrait and an event portrait; for business
task analysis time sensitivity and risk tolerance, calculating a comprehensive analysis index to judge whether time-dependent dynamic attenuation is introduced, respectively obtaining scores of all portrait
layers, fusing the scores according to weights, generating a comprehensive matching
score, and outputting a target customer set; and combining recommendation, marketing or
risk control feedback to construct a feedback
event sequence, and adjusting the multi-time scale portrait and the fusion weight. According to the method, long-term features, stage behaviors and short-term events can be distinguished, and the accuracy and
interpretability of customer portrait matching and positioning are improved.
