Knowledge base updating method and device for contract question and answer large model and medium

The invention discloses a knowledge base updating method and device for a contract question and answer large model and a medium, and relates to the technical field of artificial intelligence. The method comprises the following steps: receiving a knowledge base updating instruction triggered by the outside, and analyzing the knowledge base updating instruction to determine knowledge base updating logic; wherein the knowledge base updating logic comprises active updating and passive updating; when it is determined that the knowledge base update logic is active update, updating the large model knowledge base based on update information in a preset data source; and under the condition that the knowledge base updating logic is determined to be passively updated, based on the problem information contained in the knowledge base updating instruction, retrieving the internet information so as to update the large model knowledge base based on the internet information. According to the method, automatic updating of the
