Abstract

The invention relates to a label joint probability analysis method and system, and the method comprises the steps: obtaining label data through a plurality of channels, calculating the probability distribution of the label data according to the channel weight corresponding to each channel, and generating a label probability statistical table; grouping and combining all the label data, splitting the label probability statistical table according to the label combination to obtain a plurality of label probability sub-tables, and calculating the joint probability of all the label probability sub-tables; and calculating and obtaining a label probability matrix by integrating the joint probabilities of all the label probability sub-tables. According to the method, through probability expression of the labels, the problem that existing 0-1 label distinction degree is insufficient can be solved, the complete joint probability is estimated, all known conditions are fully utilized, and the accuracy of algorithm labels is improved.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a tag joint probability analysis method and system. Background technique [0002] In the era of big data, collecting user / product information through multiple channels to establish a labeling system has more and more applications, such as precise placement and refined operation. Tags fall into three main categories: [0003] Fact label (statistical label): the most basic and common label type, for example, for a user, its gender, age, city, constellation, active time in the past 7 days, active days in the past 7 days, active in the past 7 days Fields such as the number of times can be calculated from user registration data, user visits, and consumption data. [0004] Aggregate label (rule label): This type of label is generated based on user behavior and determined rules. For example, the caliber of "active consumption" users on the platform is defined as "th...
