This paper summarizes the background and advantage of data mining, as well as the significance of data mining in the scientific research management of colleges and universities firstly, and then discusses the theory of data mining, association rules and the ideas of main algorithm, analyzes the classic Apriori algorithm and its existing problems as well as the basic solutions. After that, this paper proposes Multi-Dimensional Apriori algorithm which is designed specially for the mining of this paper; Then describes the structure of scientific research data mining system, defines subject-oriented mining tasks, including: mining the data about research projects, mining the data about papers, mining the data about academic writings. The association mining process is implemented by programing, a number of stimulating association rules are found, interpreted and analyzed.

Since any frequent itemset is a subset of a maximal frequent itemset (an itemset is maximal frequent if it has no superset that is frequent), this paper proposes the DMFI (Discovery of Maximal Frequent Itemsets) algorithm for mining all the maximal frequent itemsets from data sets. This algorithm searches the maximal frequent itemsets in data sets from both bottom-up and top-down directions in the meantime. This paper proposes an algorithm that evaluates the boundaries on the support and confidence of uncalculated itemsets by exploiting the information provided by the calculated itemsets.

本文在经典关联规则的基础上,提出了一系列扩展的关联规则开采算法:发现关联规则的难度体现在发现频繁项目集上,事实上最大频繁项目集(其所有的超集都为非频繁项目集的频繁项目集)的集合已经包含了所有的频繁项目集,本文提出一种发现最大频繁项目集的算法DMFI(Discovery Maximal Frequent Itemsets),该算法采用自底向上和自顶向下相结合的搜索策略对数据空间进行有效的搜索。

Subsequently, in order to solve a fatal problem of surprising amount of calculating and storge of presental fuzzy inference algorithm when used to solve multi-compliacted rules, we propose the decompositional method of complicated rules and solving method of resoning result after the rules are decomposed, so that a simple algorithm of fuzzy inference on-line can be obtained and the amount of calculating and storge can largely decreased.

针对现有的模糊推理算法用于多重复杂蕴涵规则时计算量及要求的存贮量太大这一应用中致命的问题,我们提出了复杂规则的分解方法,推导了规则分解后推理结果的求取方法,在此基础上提出了模糊推理的简便算法,使得在线实现模糊推理的计算量及要求的存贮量减少若干个数量级。
