The invention relates to the technical field of
data analysis, in particular to a user portrait
label value
analysis method and
system, and the method comprises the steps: obtaining a first main user portrait
label value, and carrying out the mapping to form a first user discrete point group; generating
virtual user data, respectively inputting the
virtual user data into a first main body clustering model and a second main body clustering model to form a first
simulation discrete point group and a second
simulation discrete point group, recording a transformation vector through space fitting, identifying an unmatched discrete point group, performing segmentation and scaling
processing on the unmatched discrete point group, recording a segmentation and scaling vector, and performing segmentation and scaling
processing on the unmatched discrete point group; and performing coordinate transformation on the first user discrete point group through a transformation vector and a segmentation scaling vector to obtain a second user discrete point group, and obtaining a user portrait
label value of the second subject. According to the method, user portrait conversion of a cross-
tag system can be realized on the premise of not sharing original user data, and the tag matching problem caused by normalized
information loss is solved.
