Abstract

The invention relates to a method for discriminating house property data identity of different information sources, and belongs to the technical field of internet data analysis and mining. The identity discrimination method is based on the house data published by Lianjia, 5j5j, Zhongyuan and Maitian websites and the correlation thereof. The characteristics of the house data are analyzed, the repeated house data are removed through the three steps of regional duplicate removal, community duplicate removal and house duplicate removal, the house data are described according to the characteristicsof actual house objects, and although the described angles and modes are different, the data have very high correlation. According to the method, the house data from different websites can be duplicated, the identity of the house data from different information sources can be accurately and efficiently judged, the duplicated areas and cells can be effectively removed, the effective fusion of thehouse data oriented to multi-source heterogeneity can be achieved, and the clean and orderly data are provided for the real estate market analysis.
