(English Abstract)
The monotonically increasing nature of a data domain means that the domain expands as new elements are added over time if elements already existing in the domain are never removed. In this paper, we propose an efficient set-based similar sequence matching method that uses the monotonically increasing property. Specifically, by using the monotonically increasing property, the proposed method considerably reduces the number of candidates generated during matching and reduces the processing time needed to perform the matching. The proposed method improves the similar sequence matching efficiency by reducing the search spaces for the matching as follows: 1) determining if two given sets are likely to be above the threshold by utilizing the monotonically increasing property, 2) determining if the intersection size is likely to be above the threshold with higher accuracy by checking for the existence of common elements in the two sets. According to the experimental results, we show that the proposed method reduces the processing time and the number of candidates by about 1.7 times compared to the existing method.
