Data object sorting method and device

The invention aims to provide a data object sorting method and device. Specifically, the method comprises the steps of classifying data objects according to attribute information of main attributes ofthe data objects, thereby obtaining at least one data category; under each data category, clustering the data objects according to attribute information of key attributes of the data objects, therebyobtaining at least one data cluster; and under each data cluster, performing information fusion on attribute information of redundant attributes of the data objects. Compared with the prior art, thescheme has the advantages that after the data objects are obtained, the data objects are classified through the main attributes; the clustering processing is performed for the data objects in each data category to obtain a data cluster containing similar data objects; and the data objects in each data cluster are subjected to information fusion to obtain complete information capable of representing all the data objects in t
