Abstract: The present disclosure provides a multi-system-based intelligent question answering method and apparatus, and a device, relating to the field of artificial intelligence, in particular to the field of knowledge graph. The specific implementation solution is: determining a question category of question information in response to a question answering instruction of a user, wherein the question answering instruction is used to indicate the question information; determining a query engine corresponding to the question category, and invoking multiple question analysis systems corresponding to the query engine according to the query engine; and feeding back answer information to the user when the answer information corresponding to the question information is determined according to a current question analysis system in a process of processing the question information by sequentially using the multiple question analysis systems according to system priorities of the question analysis systems.

Abstract: A method includes by a configuration center, receiving and executing a modification task, and locally storing modified state data and/or configuration data; generating a change task according to the modified state data and/or configuration data, and adding the change task into an asynchronous task queue corresponding to each storage node; receiving a heartbeat packet sent by the storage node; and taking out the added change task from the asynchronous task queue corresponding to the storage node, and adding the taken-out change task into a return message of the heartbeat packet to send the taken-out change task to the storage node; by a storage node, sending a heartbeat packet to a configuration center; receiving a return message of a heartbeat packet sent by the configuration center, the return message of the heartbeat packet including a change task; and adding the change task into an asynchronous task receiving queue for sequential execution.
