Abstract

The invention provides a method and a device for extracting crowd portrait based on big data analysis. The method comprises the following steps: inputting the obtained big data of the crowd into a preset cluster analysis model and outputting a plurality of sub-crowd data; calculating the cluster center eigenvalue of each sub-population data; for any target sub-crowd data, determining a crowd portrait of the target sub-crowd data according to a cluster center point eigenvalue of the target sub-crowd data. The method and the device for extracting crowd portrait based on big data analysis provideby the invention, wherein, the eigenvalue of the big data of the crowd is finely selected, the number of clusters is selected through an experiment, and then the eigenvalue of the cluster center point of the crowd data is determined, the crowd portrait of the crowd data is determined, and the accuracy of the obtained crowd portrait is improved.

Description

technical field [0001] The invention relates to the technical field of big data analysis, in particular to a method and device for extracting crowd portraits based on big data analysis. Background technique [0002] In the information age, people are generating data all the time. Bus card swiping data, bank card payment data, mobile phone call data, Internet access data, etc., each person's personal data constitutes a big data set, and the data of multiple people constitutes a larger big data set, and the crowd is large. A large amount of information is stored in the data. How to analyze the large amount of big data and get the crowd portrait is very important for the management and service of the crowd. [0003] Crowd portraits can be simply understood as labels of massive data. According to the differences in the goals, behaviors and opinions of the crowd, they are divided into different types, and then typical characteristics are extracted from each type to form a type o...
