As an essential operation in data cleaning, the similarity join has attracted considerable attention from the database community. In this paper, the authors will study string similarity joins with edit-distance constraints, which find similar string pairs from two large sets of strings whose edit distance is within a given threshold. Existing algorithms are efficient either for short strings or for long strings, and there is no algorithm that can efficiently and adaptively support both short strings and long strings. To address this problem, they propose a partition-based method to find the string similarity for joint operation.
