User tag identification method and device based on stack technology

The invention relates to the field of data processing, and discloses a user tag identification method and device based on a stack technology. The method comprises the following steps: monitoring a behavior log of a target user to a website in real time, and establishing a stack process corresponding to each preset behavior in response to any monitored preset behavior of the target user; sequentially storing the monitored continuous behavior records taking the preset behaviors as initial behaviors into corresponding stack processes according to a time sequence; after the target user closes the website, according to a sequence from the top to the bottom of the stack, reading a specified number of behavior records from each stack process, and identifying a tag corresponding to a preset behavior based on the read behavior records; and after the target user opens the website again, returning to the operation of sequentially storing the monitored behavior records taking the preset behaviors as the initial behaviors
