AI Technical Summary
Existing business document retrieval methods suffer from low retrieval efficiency or low accuracy in the financial field.
A dual-tower model architecture is adopted for interactive learning, and a multi-attention mechanism is combined to perform vector encoding on the set of documents to be retrieved in the financial field. The vector representation capability of the model is improved through multi-stage training, including multi-stage general training of a pre-built information extraction model to obtain a standard dual-tower model, and multi-attention dense vector encoding and query vector encoding are performed using a standard document model, and finally document retrieval is performed.
It improves the accuracy and efficiency of document retrieval, especially in the financial field, where a single document can better match different queries, enhancing retrieval accuracy while maintaining the retrieval efficiency of the traditional dual-tower model.
