怎样优化金融风控场景中的关系网络分析效率?

2025-09-05 1.6 K

金融风控图谱优化方案

提升分析效率的关键措施:

  1. 索引优化:为关键属性创建复合索引CREATE INDEX ON :Transaction(amount, time)
  2. 图算法选择:针对不同场景:
    • 欺诈检测:使用graph.algorithm.community()识别可疑团体
    • 洗钱分析:应用graph.algorithm.pagerank()找出资金枢纽节点
  3. 混合查询:结合语义过滤和时间窗口WHERE r.relation_type=''transfer'' AND r.date BETWEEN date()-duration(''P1M'') AND date()

性能提示:对超大规模图谱建议启用graph.enable_cache()缓存常用查询路径。
