Abstract


Along with the rapid development of information technology , so that the surge in the amount of data in various fields , but the valid information that can be obtained is limited . Get valuable potential in vast amounts of data , is a common issue facing contemporary . Data mining is a new understanding of the data , and smart means understanding data , association rules is one of the most important technology in data mining [ 1 ] . On the basis of technical research association rule mining , carried out the data analysis and mining research based on association rules . First , for the shortcomings and deficiencies of the association rules , the use of a matching degree to replace the confidence generated matching degree rule not only has a higher correlation , but also to reduce the generation of redundant rules [2-5 ]. Secondly , on the basis of the analysis of the classic Apriori algorithm , the improved algorithm of Apriori an effective based on Boolean matrix [ 2] . The algorithm is applied Boolean matrix thought just to scan the database once , you can get frequent itemsets , greatly improving the efficiency of the algorithm . Finally, the combination of the characteristics of the classroom teaching quality assessment data association rules algorithm applied to the determination of the quality of classroom teaching evaluation index system : teaching assessment information for the data source , use of improved Apriori algorithm determine the quality of teaching scientific evaluation index system .
