Method and device for determining common associated object

The invention relates to the technical field of computers, in particular to a method and device for determining a common associated object, and the method comprises the steps: obtaining the associatedobject information of N target objects, N being greater than or equal to 2; determining the occurrence frequency of each associated object information in all associated object information; and if itis determined that the occurrence frequency of any associated object information in all associated object information is N, determining that a target object corresponding to the associated object information is a common associated object of N target objects. According to the method, the common associated objects of the large-scale target objects can be calculated without sequential comparison, sothat the calculation amount of determining the common associated objects is reduced, the efficiency of determining the common associated objects is improved, and the time cost and the calculation costare reduced. 本发明涉及计算机技术领域，尤
