BIG DATA-BASED PROFILE ANALYSIS METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/248843
Kind Code:
A1
Abstract:
A big data-based profile analysis method and apparatus, a computer device, and a storage medium, relating to the field of big data processing. Said method comprises: acquiring a profile analysis request, and on the basis of the profile analysis request, obtaining, by means of filtering a user profile database, profile data to be analyzed which satisfies a target filtering condition, said profile data comprising profile factors to be analyzed and a factor value to be analyzed corresponding to each profile factor to be analyzed (S201); performing standardization processing on the factor values to be analyzed, to acquire standardized factor values corresponding to said profile factors (S202); performing, by means of a CRITIC method, weight analysis on said profile factors and the corresponding standardized factor values, to acquire a weight value corresponding to each profile factor to be analyzed (S203); filtering said profile factors according to the weight value corresponding to each profile factor to be analyzed,so as to determine profile factors to be selected (S204); performing, by means of a PCA method, dimension reduction on the profile factors to be selected, and determining the first M profile factors to be selected after dimension reduction as target profile factors (S205); and clustering, by means of a Kmeans clustering algorithm, the target profile factors and the corresponding standardized factor values, to obtain user group attributes, and querying a target object corresponding to the user group attributes. Using said method to perform profile analysis improves the clustering efficiency.
