Abstract:

Data mining techniques are employed to analyze the ancient pottery data in Central China to explore the evolution of ancient pottery and the origins of roughly inheritance relation of the Central China between each type of culture,which is of great significance in archeology and anthropology.As the major step of data mining,data preprocessing can improve data quality,thereby helping to improve the accuracy and efficiency of the subsequent mining process.Because the ancient pottery in Central China has the features of complex types with large amount of incorrect,incomplete and inconsistent data,the data preprocessing techniques of data cleaning,data integration and data transformation are used,thereby greatly improving the quality of data mining models.

Key words: data preprocessing;data cleaning;data integration;data transformation
