金融界2025年4月26日消息，国家知识产权局信息显示，泸州老窖集团有限责任公司;电子科技大学申请一项名为“一种基于社区划分的供应链风险知识图谱规模压缩方法”的专利，公开号CN119862242A，申请日期为2024年12月。
专利摘要显示，本发明公开了一种基于社区划分的供应链风险知识图谱规模压缩方法，包括S1：获取目标实体和目标实体之间的而关系，构建风险知识图谱；S2：将风险知识图谱的数据导出，构建拓扑结构图；S3：基于得到的拓扑结构图对风险知识图谱进行社区划分，获取划分后的图谱和被阻断的边集合；S4：基于图神经网络构建链接预测模型，并根据划分后剩余的图谱数据进行模型训练；S5：通过训练好的链接预测模型对被阻断的边进行预测；S6：基于预测结果进行筛选，得到筛选后的边集合，完成图谱规模压缩。本发明实现了以缩减图谱的整体规模为压缩目的，同时减少了边的移除，降低了多跳关联搜索的复杂度。
