Identification and Inspection of Approximately Duplicated Records Based on Data Warehouse

Peng Lu(Department of Information Engineering,Wuhan University of Science and Technology City College,Wuhan 430083)  
In order to cleaning approximately duplicated records,first it is needed to identify the identity of the same entity,there are two main methods: one is to decide whether it is the same entity actually by comparing the similarity degree between the whole strings;another is to match based on the fields of the records.First set a text similarity,and then decide whether the two records are the same according to it,if the text similarity between records is larger than the pre-specified threshold value,then judge they are repeated,and vice versa.
