As mentioned, the address field was longer than that of the company name field on average, and it contained more duplicated documents.
we expect that the proposed method is effective in the following situation: (i) the length of each document (record) is short, (ii) the number of duplicate documents has been reduced beforehand by simple filtering methods such as deleting exact match documents or documents different only in space, and (iii) detecting the remaining duplicate documents by using a deep similarity function such as edit-similarity.
