TIME-SERIES DATA SEARCH PROGRAM, TIME-SERIES DATA SEARCH DEVICE AND TIME-SERIES DATA SEARCH METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique for searching time-series data of the other time similar to time-series data of a designated time, and presenting the searched similar time-series data in an easy-to-understand manner.;SOLUTION: In the search program, a time-series data storage part 20 stores time-series data. In a time-series data search processing part 10, a display processing part 11 displays time-series data on a display device 30, and receives selection of search object data by a user. A search object designation processing part 12 receives designation of conditions such as a threshold for determining similarity and importance of each numerical data, the setting and performs setting thereof. A search processing part 13 calculates a similarity by a similarity calculation processing part 14 based on a difference of each numerical data or a time difference between the search object data and each time-series data, and lists up time-series data the similarity of which satisfies the designated threshold condition. The display processing part 11 displays the time-series data while highlighting the listed similar data.;COPYRIGHT: (C)2009,JPO&INPIT
