METHOD AND APPARATUS FOR GENERATING INCIDENT GRAPH DATABASE

method and apparatus for generating incident graph database are provided, one of methods comprises, generating incident coverage using an apparatus for generating an incident graph database when the incident coverage comprising a first node and a second node connected by a first edge and constituting an incident graph database does not exist, determining whether each of the first node and the second node has additional connection based on a relationship type of the first edge using the apparatus for generating an incident graph database, expanding the incident coverage to further comprise an expansion node using the apparatus for generating an incident graph database, repeating the generating of the incident coverage, the determining of whether each of the first node and the second node has the additional connection, and the expanding of the incident coverage on all edges included in the incident graph database using the apparatus for generating an incident graph database and generating a first incident node in which all nodes and edges included in the incident coverage are connected using the apparatus for generating an incident graph database, wherein the expansion node is a node connected to the first node or the second node determined to have the additional connection.
