城市治理 · 时空事件去重

同一个事件被上报十次,系统应该生成十个任务吗?

08:00—08:09,同一路口的积水被市民、热线、摄像头和巡查人员连续上报。十次上报不是十起事故,也不应触发十次重复派单。

one incident + ten evidence sources → one verified dispatch task

十个上报点,聚集在同一路口

事件最大偏移18.97米,小于30米阈值同一事件类型 · 同一路段 · 同一十分钟窗口
语义签名一致
true
空间阈值内
true
时间窗口内
true
true AND true AND true → duplicate_reports_verified = true

去重不是删除,而是合并任务、保留证据

10来源上报
1处置任务

evidence_source_count = 10

所有来源ID都被保留,新上报继续关联到已有事件,并提升事件置信度,而不是被静默丢弃。

市民App × 512345热线交通摄像头巡查人员公交驾驶员交警

若事件类型不同、位置超出阈值或时间间隔过长,就不能自动合并,应生成新事件或进入复核。

第一步:让模型选择处置动作

得到模型建议后返回本页,选择对应动作并验证。

GT17演示单一事件簇。真实城市事件去重还需要文本语义、道路拓扑、事件演化、图片相似度、来源可信度和人工复核机制。
