The invention provides a user portrait construction method and device based on big data and a storage medium. The method comprises the following steps: establishing a user portrait label system; collecting user data and storing the user data in an entity table and a fact table which are pre-constructed in a data warehouse; carrying out ID-Mapping association on the entity table and the fact table to realize aggregation of user data; and based on a user portrait label system, for each label, obtaining user data related to the label from a data warehouse, processing the user data, and storing the user data in a user portrait database. According to the invention, the data warehouse technology is adopted to realize the storage and processing of massive user data, and the processing demand of the big data era on massive data is improved. Besides, the non-structural user data is processed by adopting a data mining tool including a machine learning algorithm, so that richer tag data is obtained, and the tag richness of the user portrait is improved.
Description
technical field [0001] The present invention relates to the field of big data. Specifically, the present application relates to a method and device for constructing user portraits based on big data. Background technique [0002] After the Internet has entered the era of big data, user behavior has brought a series of changes and reshaping to the company's products and services. "of. A large amount of original data and various business data are stored in the enterprise, which is the true record of the enterprise's business activities. How to use these data more effectively for analysis and evaluation has become a problem for the enterprise based on the background of a larger amount of data. With the research and application of big data technology, companies are increasingly focusing on how to use big data to serve refined operations and precise marketing. To do refined operations, they must first establish their own user portraits. [0003] User portraits, that is, user inf...
