Abstract
A method of building a knowledge graph, performed by a processing device, includes: classifying news articles to a main event associated with sub events, using the main event as a first node of the knowledge graph, using the sub events as second nodes of the knowledge graph respectively, connecting the second nodes to the first node, extracting event summaries from the news articles respectively according to a template, using the event summaries as third nodes of the knowledge graph respectively, and connecting each of the third nodes to one of the second nodes according to association between the event summaries and the sub events, extracting commenter identities from the event summaries, and using the commenter identities as fourth nodes of the knowledge graph, and connecting each of the fourth nodes to one of the third nodes.
