The key technology of the similar semantic attribute clustering process in the heterogeneous database was researched.On the basis of the term frequency-inverse document frequency,the processing method of bin frequency-inverse document bin frequency was proposed,which was applied in similar semantic attribute clustering prosess of the text information and numerical information.The results show that the method using term frequency–inverse document frequency and bin frequency-inverse document bin frequency is effective to the process of the similar semantic attribute clustering in the heterogeneous database.
