• in response to the feedback mode being manual feedback, determine a target operator through the call center to feed back a call of the target customer;
• and
• in response to the feedback mode being automatic feedback, determine, using a knowledge map, a feedback content through the call center based on the service category corresponding to the call message, and send the feedback content to the target customer;
• wherein nodes of the knowledge map include at least one of a customer, a service category, a feedback content, or an area, and a node feature includes a real-time pipeline network situation in a position area of the customer;
• edges of the knowledge map include an edge between the customer and the service category, an edge between the service category and the feedback content, an edge between the customer and the feedback content, or an edge between the customer and the area.
