Method and Apparatus for Processing Knowledge Graph

An apparatus for processing knowledge graph, comprising:

• an acquisition unit, configured to acquire multiple groups of entity data and multiple candidate relationship templates from a text to be analyzed, the candidate relationship template being configured to describe a relationship between multiple pieces of entity data in a group of entity data;
• a first determination unit, configured to, for each group of entity data, determine the number of times for which the candidate relationship template matched with the group of entity data in the text to be analyzed is matched successfully;
• a second determination unit, configured to determine a probability of correct matching between each group of entity data and each candidate relationship template according to the number of times for which each group of entity data is matched successfully with each candidate relationship template;
• and
• a supplementing unit, configured to supplement an entity data relationship in a knowledge graph according to the probability of correct matching between each group of entity data and the candidate relationship template.
