The set-based similar sequence matching method using the monotonically increasing property utilizes the property that elements included in the data domain are continuously added over time without removing. By using the monotonically increasing property, the existing method reduces the computation cost for intersection which takes large proportion of the cost for the set-based similar sequence matching. However, for utilization of the monotonically increasing property, it is necessary to check whether the creation time of given sets satisfies a specific condition, which causes the performance degradation in the process of checking all the stored sets one by one. To solve this problem, we propose the domain time inverse index structure that indexes sets by the creation time of set. Using the proposed index structure, we can fastly find only the sets that satisfies the specific time condition, thereby increasing the efficiency of using the monotonically increasing property. Through experiments, the proposed set-based similar sequence matching using the domain time inverse index structure shows the performance improvement through the reduction in processing time by about 6 to 15 times compared to the existing method. |
