面向离散制造数据底座的层级部分语义对齐方法及系统

本发明公开了一种面向离散制造数据底座的层级部分语义对齐方法及系统。现有实体对齐与模式匹配方法仅关注等价匹配，难以处理字段名称相似但业务阶段不同的语义混淆，且缺少跨层级约束和无效匹配机制。本发明将标准数据底座图与业务语义图分离建模，在字段、表和数据关系三个层级建立候选映射矩阵并引入no‑match候选；构造多源证据向量生成候选评分，通过高置信锚点计算业务邻域一致性并更新证据向量，最后施加层级一致性、关系端点一致性和no‑match一致性约束，输出高置信候选、待复核候选和no‑match列表。本发明能够同时处理三个层级的候选映射，避免技术字段强制对齐到业务语义单元，提高了语义承载关系识别的准确性和稳定性。
