摘要 |
<p><P>PROBLEM TO BE SOLVED: To keep a computing cost low in determining the similarity of time-series data. <P>SOLUTION: The time-series data are narrowed down by a narrowing down part 3 by using multi-dimensional index structure, and a distance between dimensionally compressed time-series data is found by a similarity determination part 4, and the data are determined to be similar in the case that the distance is at most a prescribed value. Thus, a computing cost is kept low by conducting similarity determination using the dimensionally compressed time-series data. High-precision dimensional compression is realized by computing the average and standard deviation of the time-series data for each frame as a dimensionally compressing means. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
