UnverifiedSemantica supports bitemporal facts, simultaneously tracking when a fact is true in the real world and when it is recorded in the system, enabling point-in-time graph snapshot playback of history.76% similarUnverifiedBitemporal modeling requires each memory record to carry two independent timestamps: event time (the time the event actually occurred in reality) and system write time (the time the database recorded the event).74% similarUnverifiedExtraction of temporal and event expressions is a foundational task in temporal reasoning, widely applied in information extraction, knowledge graph construction, and event tracking scenarios.72% similarUnverifiedPoint-in-Time（PIT）数据系统需要对每个数据点同时记录事件发生时间和数据可知时间两个时间戳71% similarUnverifiedEvent timestamps record the moment something actually happens, while processing timestamps record the moment the system receives it; inventory-type applications usually rely on event timestamps and set a reasonable time window to tolerate out-of-order arrival.70% similar
