The Research of Methods in Data Mining

Knowledge discovery in databases and data mining aim at semiautomatic tools for analysis of large data sets. We consider some methods used in data mining, concentrating on levelwise search for all frequently occurring patterns. We show how this technique can be used in various applications. We also discuss the possibilities for compiling data mining queries into algorithms, and look at the use of sampling in data mining. At the end, we list several research problems in data mining and knowledge discovery.
