With the advent of the era of big data, Internet technology has developed rapidly. In order to stand out among competing products and gain competitive advantage, the trend of excessive competition gradually appears in Internet enterprises, which leads to many problems, such as the rise of marketing costs and the decline of marketing performance. To solve the above problems, this paper relies on the user data of beauty camera, uses LDA model to establish user portrait, and obtains the corresponding subject distribution by extracting subject words; Expand the selected corresponding words into the feature space, improve the user features, and then use the SVM classification algorithm to distinguish the basic attributes of users, so as to construct the user portrait.
