Problems solved by technology
However, the knowledge base lacks the necessary organization and abstraction. When the volume of the knowledge base becomes larger and larger, the cost of maintaining the knowledge base will gradually increase until frequent errors or even unmaintainable errors occur during the maintenance process, which seriously affects the Improving the effect of robot question answering

Embodiment Construction
[0048] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.
[0049] figure 1 It is a schematic diagram of an implementation scenario of an embodiment disclosed in this specification. This implementation scenario involves the recall of knowledge points based on the business map. refer to figure 1 , the business map is a tree structure sorted out by the operation personnel, and organizes various knowledge points of the knowledge base in a hierarchical form. In the embodiment of this specification, multiple business maps can be established in advance, and each service map 100 includes multiple nodes organized into a tree-like hierarchical structure according to business dimensions, and the multiple nodes include root nodes 11, intermediate nodes 12 and The leaf node 13, the root node represents a business with a specific business type, the intermediate node represents business knowledge keywords of different level...

The embodiment of that present specification provide a method and apparatus for knowledge point recall, The methods include: first, the matching service corresponding to the user question is determined, The matching service is a service with a specific service type, and then selecting the root node from multiple service maps as the service map of the matching service, the service map is determinedas the matching service map corresponding to the user question, in the matching service map, By using the pre-trained rule matching model, matching knowledge points matching with the user questions are determined, and finally, knowledge points recalled for the user questions are determined based on the result of determining matching knowledge points, so that the robot question answering effect iseffectively improved when the knowledge points are recalled for the user questions.
Description
technical field [0001] One or more embodiments of this specification relate to the computer field, and in particular to a method and device for recalling knowledge points. Background technique [0002] In the Q&A system of intelligent customer service, when the customer (that is, the user) interacts with the robot, the user’s question sentence is colloquial and simplified. When recalling knowledge points for the user’s question sentence, improving the matching ability and effect of the customer service robot will have a significant impact on the entire system. The question answering system is very critical and directly affects the service experience of the question answering system. However, as the business logic becomes more and more complex, the method of simply relying on the matching model to push the most relevant knowledge points to the user's question description gradually encounters a bottleneck. On the one hand, with the increase of models, the maintenance of each m...
