| Abstract: | Problems of data pretreatment about repeat records in the data warehouse were studied and the definitions of attribute repeating measuring, record repeating measuring etc. were brought forward based on the attribute sets. The generic algorithm named IRA and its generalized algorithm GIRA was described for identifying the repeat records. To dispose the noises of repeat record sets, an algorithm of INA based on distance was put forward. And examples to show that the implementation of these algorithms were indicated in detail. |
