AI Technical Summary

Technical Problem

Existing search augmentation generation (RAG) systems lack adequate verification of document quality, leading to potential risks in the generated results, which could have serious consequences, especially in high-risk areas. Furthermore, they fail to effectively address consistency checks and security issues between documents.

Method used

A multi-dimensional verification mechanism is adopted, including user input and query parsing, multi-source document retrieval, credibility assessment and security verification, document consistency detection, and result output and traceability modules. Natural language processing, hybrid retrieval, semantic comparison, and log system are used to ensure the accuracy and credibility of the generated content.

Benefits of technology

It effectively reduces generation errors caused by the use of unreliable or erroneous documents, improves the quality and reliability of the generated results, ensures that the generated content is based on authoritative, up-to-date and conflict-free literature, and enhances the interpretability and adaptability of the system, making it particularly suitable for the legal and medical fields.

Abstract

The invention discloses a retrieval enhancement generated document screening system and method fusing a verification mechanism, and relates to the technical field of document screening, the system comprises a user input and query analysis module for extracting key information through natural language processing, and converting the key information into a high-dimensional semantic vector, a meta-tag and a keyword set; the multi-source document retrieval module is used for obtaining documents from multiple data sources through mixed retrieval and generating a candidate set through preliminary screening and sorting; the credibility evaluation and security verification module is used for generating scores and labels after multi-dimensional evaluation and screening qualified documents; the document consistency detection module is used for detecting document conflicts, processing and sequencing, and ensuring logic consistency; the document acquisition and generation module is used for inputting qualified documents into a generation model and generating answers with references; and the result output and tracing module is used for outputting answers and recording whole-process data to ensure traceability. The invention aims to ensure the accuracy and credibility of the generated content through a multi-dimensional verification mechanism.
