摘　　要：依赖于专家知识的传统风险评估方法通常为静态评估,无法满足不可移动文物多变风险的识别与评估需求.提出了一种基于语义路径编码异构图网络的文物安防动态风险评估方法,通过构建文物安防知识图谱,规范化存储风险相关的影响因素,然后采用语义路径编码对安防知识图谱中的实体特征进行聚合,帮助网络提取更准确的实体知识表示,提高了风险等级分类的准确率.此方法在多个国家重点文物保护单位中进行了测试,风险等级分类的准确率为94.74%,和专家评估的结果基本吻合,对文物的风险管控和安防管理具有一定的指导和参考价值.The traditional risk assessment methods relying on expert knowledge are usually static,which cannot meet the needs of identification and assessment of variable risks of immovable cultural heritage.A dynamic risk assessment method for cultural heritage security based on semantic path coding heterogeneous graph network is proposed.By constructing a cultural heritage security knowledge graph,the influencing factors related to the dynamic risk of cultural heritage security are stored in a normalized way,and then the entity features in the security knowledge graph are aggregated using semantic path coding,which helps the network to extract a more accurate representation of the entity knowledge,and improves the accuracy of the risk level classification.The method is tested on several national key cultural heritage protection units,and the accuracy rate of risk level classification is 94.74%,which is basically consistent with the results of expert assessment,and it has certain guidance and reference value for risk control and security management of cultural heritage.
