Abstract:

With the development of Internet, the research of Internet data mining becomes hot. In the paper, the XML formats of non-structural data of the Intern et are selected and stored, and then are transformed into structural data and stored in the SQL Server database. The minimum association rule set is produced by the association rules which are based on data-warehousing. It can decrease the weak association rules effectively and reduce the frequent candidate item sets in a large scale. Finally, based on the classical Aprlori algorithm, the upward closure property of weak rules is utilized to develop a c orresponding algorithm that proves to be efficient.
