Application Research Of Data Mining Technology In Teaching Appraisal

As there are large amounts of data in the databases, it is very important for us to find the useful information from the database, and data mining technology is an efficient solution to this problem.This paper aims at studying the way of combining data mining technology with teaching appraisal and the way of looking for useful information hiding behind the data from the large amounts of data. First, the author pointed out the research content and motive of this paper, analyzed and compared the relevant content of data mining technology, then determined to choose the method of decision tree to realize data mining concretely. Secondly, the author elaborated the analysis and design method of teaching appraisal data mining system, introduced the realizing process of the system, then tested the system using one group data of the system. At the meantime, the author drew the final conclusion by analyzing the result. At last, the author put forward the imagination of further research of this system, thus offered the technique support of the next work of this system.
