摘要
Rough集是一种处理不精确、不一致、不完整的各类数据,并从中发现隐含的知识,揭示其潜在规律的数学方法。将Rough集引入到教师考评系统中,对考评系统中各项考核指标进行分析并约简,去除了冗余指标,提取出重要考评指标,然后进一步分析属性约简后的考评数据,从数据中发现规律并提取出考评的一般规则。
Rough set is a mathematical tool which can find the hidden knowledge and rules from inaccurate data,inconsistent records and incomplete information.With the application of Rough set theory in teacher evaluation system,removes redundant evaluation indexes while main attributes are retained.Then having the aid of further research on the reduction data,discovers general rules of teacher evaluation and extracts the general rules of evaluation.
