N-GRAM BASED KNOWLEDGE GRAPH FOR SEMANTIC DISCOVERY MODEL

摘要

A method processing alarm messages generated by a computer network administration system includes, for each one alarm message of a plurality of alarm messages, selecting a plurality of n-grams from the one alarm message, assigning each of the plurality of n-grams to a node in a knowledge graph, generating a node weight for each node in the knowledge graph based on a popularity of the n-gram associated with the node, generating an edge weight for each of a plurality of edges connecting nodes in the knowledge graph to each other, and extracting semantic relationships between nodes in the knowledge graph based on the node weights and the edge weights. The alarm messages are grouped into clusters based on the extracted semantic relationships.
