USER INTEREST PROFILING METHOD AND RELATED DEVICE

A user interest profiling method and a related device, relating to the technical field of artificial intelligence. The user interest profiling method comprises: generating a registration feature vector of a user according to a determination result of whether a plurality of websites have registration information of the user; determining a first probability value of each interest tag of the user by using a clustering method and according to the registration feature vector of the user; crawling a plurality of target named entities of the user from each target website; calculating a second probability value of each interest tag by using a trained neural network; calculating a third probability value of each interest tag on the basis of a statistical method; determining the largest value among the first probability value, the second probability value and the third probability value of each interest tag as a target probability value of the interest tag; and determining the interest tag having a target probability v
