(English Abstract)
Time-series data are sequences of real numbers, sampling a sequential data into the fixed time intervals. Common examples of time-series data are the music data, video data, electroncardiogram data, and the data of stock graphs. A time-series data can be classified into the data sequence stored in a database and the query sequence received by users. For querying a time-series database, a ranked subsequence matching program is used to find top-k subsequences which are the most similar to the query sequence from the data sequence. The goal of this paper is to develop a visualization tool which can improve and facilitate the usage of the ranked subsequence matching program of the existing console based systems, in spite of the insufficient user¡¯s recognition and understanding about the matching method. Specifically, the proposed tool provides five different visualization functions in the user interface which can help user easily exploit the matching program.
