基于递归树形遍历的大模型长序列抗幻觉生成方法及系统

本发明公开了一种基于递归树形遍历的大模型长序列抗幻觉生成方法及系统，涉及大语言模型内容生成技术领域。所述方法由大语言模型执行以下步骤：基于目标内容的摘要及其核心知识点构建包含根节点、中间节点和叶子节点的多级递归知识树；递归遍历知识树，基于父节点和相邻节点上下文约束输入大语言模型生成原始内容；仅在叶子节点触发RAG检索并对原始内容校验融合；全部叶子节点生成后自底向上回溯审核，逐层计算幻觉偏差值并修正超标节点，直至所有节点偏差值均不大于阈值时输出目标长序列。本发明通过知识树全局约束、延迟RAG检索和双向闭环审核机制，有效抑制大模型长序列生成的内容幻觉，大幅提升内容逻辑自洽性和事实准确性。
