Recently, time-series data, such as stock exchange rates and weather data, has widely been used in many fields. Similarity search of time-series data is important because it is useful for predicting data changes and for searching for common sources. In this paper, we propose a new similarity search method of time-series data using both Discrete Fourier Transform (DFT) and Wavelet Transform (WT). A method of reducing time-series indexing size, using a correlation coefficient, is also presented.
