基于时事折换图的因果知识量化分析方法
Quantitative analysis method for causality knowledge based on time-event exchange diagram
【摘要】 针对目前协同因果事件族的知识分析缺乏时态信息和量化手段等问题,提出基于时事折换图的因果知识量化分析方法。首先运用时事折换思想建立包含时态信息的因果知识事件域描述机制,然后考虑原因事件对结果事件发生冲击影响和时间累积影响,提出因果度、依赖度、影响度三种指标并推出其计算公式,实现了对因果知识的量化描述和双向推理。应用实例表明该方法具有高效、细致、直观优点。
【Abstract】 For the void of time information and quantitative methods of the knowledge analysis for conjunction causality events,a quantitative analysis method based on time-event exchange diagram was proposed.Firstly the time-event exchange thought was adopted to establish the description mechanism that contained time information and based on event domain of causality knowledge.Then the happening and cumulate time influences of the cause event to the result event are considered.Afterwards the causality-degree,rely-degree and effect-degree including their calculating formulas are introduced which realize the quantitative description and bidirectional reasoning of causality knowledge.An example of application demonstrates that the method has high efficiency,elaborate and visual advantages.
【Key words】 time-event exchange diagram; causality knowledge; quantitative analysis; causality-degree;
