Abstract

The invention discloses a knowledge base question adding method based on a vector search engine, and the method comprises the steps: extracting scene questions in each scene of a knowledge base, converting at least one similar question of each scene question into a feature vector, and storing the feature vector into a Milvus library; storing the feature vector of each similar question in the Milvus library, and establishing an index; obtaining a newly-added question, converting the newly-added question into a feature vector, conducting similarity retrieval on the feature vector of the newly-added question in the Milvus library to obtain a first similar question and the similarity probability, wherein the similarity probability of the feature vector of the first similar question and the feature vector of the newly-added question is the highest; and determining whether to add the newly added question to the Milvus library or not based on the similarity probability.

Description

technical field [0001] The present application relates to the knowledge base field, in particular to a method and device for adding knowledge base questions based on a vector search engine. Background technique [0002] In the intelligent customer service scenario, user intent recognition is involved, and the customer service responds accordingly according to the user intent. Standard questions (intentions) and a large number of similar questions are stored in the knowledge base. After the ALBERT-based intent recognition model is launched, the AI ​​trainer needs to continuously adjust the knowledge base data (new, modified) according to the online recognition effect or some badcases. , delete, etc.). For the new problems in the knowledge base, in order to reduce the workload of AI trainers and avoid some mistakes in the manual process, algorithms can be used to judge which data needs to be added, so as to assist trainers to work more efficiently. [0003] In the existing i...
