Perception determination method and device and server

The invention provides a perception determination method and device and a server, and belongs to the technical field of communication. The method comprises the following steps: after a first event corresponding to a first user is completed, obtaining a perception coefficient of the first event according to a perception coefficient of a second event, the total number of service events of the first user, an influence coefficient of the first event, the number of service events with the same type as the first event in a customer life cycle of the first user and a first interval; according to the perception coefficient of the first event, determining at least one of the service perceptibility of the first user, the network perceptibility of the first user and the negative event perception hidden danger value of the first user, wherein the second event is a last service event adjacent to the first event, the second event is a service event corresponding to the first user, and the first interval is a time interval
