In traditional information retrieval, the basic index of the system: Recall (Recall) and precision ratio (pricision), recall is the number of related documents retrieved and the ratio of all relevant documents in the document library; The precision ratio is the percentage of the number of related documents retrieved and the total number of documents retrieved. For a retrieval system, recall rate and accuracy can not be the same: high recall rate, low precision, high precision, low recall. For
