摘要 |
Provided is a join processing device that performs a similarity join process to plural tuples using an edit distance threshold value tau (positive integer). The join processing device includes a join processing unit that excludes, from a target of edit distance calculation, a pair of tuples that do not have any common character in an end portion ranging from a head character or a tail character to a (tau+1)th character in a join key string in each of the tuples. |
