Abstract: This disclosure relates generally to incident ticket management, and more particularly to system and method for resolving incident tickets. In one embodiment, a method is provided for determining a resolution for an incident ticket. The method comprises dynamically determining a signature of the incident ticket based on a description of the incident ticket, and determining a resolution code based on the signature using a knowledge graph model. The knowledge graph model is derived, from a plurality of past incident tickets and a plurality of corresponding resolutions, by determining a set of unique signatures and a set of corresponding resolution codes.
