Title:
TIME-SERIES DATA PROCESSING DEVICE, TIME-SERIES DATA PROCESSING SYSTEM, AND TIME-SERIES DATA PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/207350
Kind Code:
A1
Abstract:
An event waveform extraction unit (3) extracts an event waveform from time-series data. A co-occurrence degree calculation unit (4) calculates a co-occurrence degree of the event waveform between time-series data. A group classification unit (5) classifies the time-series data into groups corresponding to the co-occurrence degrees of the event waveform. An event information generation unit (6) determines a time at which the periods of generation of the event waveform overlap between the time-series data included in a group, and generates event information which specifies an event related to the event waveform on the basis of the determined time.
