    • An event type estimation system includes a log aggregation unit that generates time-series data representing the fluctuation in traffic to a site from log data, a deviation testing unit that extracts an interval showing an anomalous fluctuation from the time-series data, a waveform decomposition unit that optimizes a peak waveform, a normal waveform and a vertical waveform set by a waveform setting unit, in order to approximate the fluctuation in traffic in the interval extracted by the deviation testing unit with a composite of the peak waveform, the normal waveform and the vertical waveform, and an event determination unit that determines the type of event that caused the anomalous fluctuation, based on the waveforms optimized by the waveform decomposition unit and the rules of a rule recording unit. The event type estimation system is thereby able to extract access fluctuation anomalies from log data and estimate the type of event that caused the anomalous fluctuation.
    • 事件类型估计系统包括:日志聚合单元,其从日志数据生成表示与站点的流量波动的时间序列数据;偏差测试单元,从时间序列数据中提取表示异常波动的间隔;波形分解 单位,其优化由波形设定单元设定的峰值波形,正常波形和垂直波形,以便用偏差测试单元提取的间隔中的交通波动近似,其中峰值波形,正常波形和 垂直波形和事件确定单元,其基于由波形分解单元优化的波形和规则记录单元的规则来确定引起异常波动的事件的类型。 因此,事件类型估计系统能够从日志数据中提取访问波动异常并且估计引起异常波动的事件的类型。
