Real-time user portrait description method and device, computer equipment and storage medium

The invention discloses a real-time user portrait description method and device, computer equipment and a storage medium, and relates to the technical field of user portraits. The method comprises the following steps: acquiring behavior data and product data of all users; storing and sorting the behavior data and the product data to form an initial data graph; acquiring a user group B associated with the user A based on a graph migration algorithm of the initial data graph; obtaining a new behavior feature of the user A, and screening a user group B'with a tag corresponding to the new behavior feature from the user groups B; calculating the label value score corresponding to the new behavior feature of the user A based on the label value score corresponding to the new behavior feature of each user in the user group B '; judging whether the label value score of the user A is greater than a threshold value or not; and if the new behavior characteristic is greater than the threshold value, the user A has the lab
