摘　　要： 为了分析影响毕业论文质量的关键因素,以毕业论文评定表的原始数据为基础,利用粗糙集理论与算法对知识进行简化。对决策表采用了基于差别矩阵的属性约简算法、属性重要度分析、值约简和规则提取等操作,去除决策表中冗余的属性和属性值,得到了影响毕业论文质量的关键因素,对撰写好毕业论文做出了预测分析。 To analyze the impact of key factors on the quality of dissertations, the paper applies rough sets theory and algorithms to simplify knowledge with the original data in the assessment tables in dissertations as its basis. Such operations as discernible matrix-based attribute reduction algorithm, the analysis of attributes-impor- tance and rules extraction have been adopted. By abstracting the redundant attributes and attributes value from the decision table, key factors affecting the quality of dissertations have been found and predictable analysis on the quality of dissertations could be made.
