Research On Sampling Of Tax-checking Based On Data Mining

To implement tax-checking sampling and analysis enterprise, we use data mining technology. This technology can help us find the unhonest enterprise and improve efficiency of inspection and reduce the cost.This paper focuses on the main contents as follows.(1) The paper explained the research background of tax-checking sampling. In addition, the paper analyzed the basic theory of tax check domestic and foreign and the basic konwledge of data mining .Finally, we explained the theory of software engineering and data warehouse.(2) There is a introduction of requirements analysis and system function, and particular discuss the data analysis and process analysis of tax check.(3) This paper built the tax data warehouse in detail, using th theory and knowledge of data warehouse and tax checking sampling.(4) Based on the data warehouse of tax check, the paper mines the association rules of data mining, using the Apriori algorithm.According to the technology of data mining, this paper set up a system of tax-checking sampling, which makes up the shortcomings of artificial tax check and improves efficiency of inspection.
