  11. This part put forward the system conception of kdd and the apriori algorithm. then evolved the create - frequent - set algorithm which was fit for the freight agent management system. because of the shortage of efficiency, 1 improved the algorithm. because some of the items were not boolean variables, 1 need the quantitaitve attributes association rules discovering algorithm. in general, there had the levels among the items, so multilevel association rules existed. after perfecting the algorithmic need interpret and evaluate the knowledge. in the end, 1 discussed the privacy and security of kdd. the fifth part described the future problems and prospect

    第四章是論文的主體，著重介紹知識發現的全過程，按照semma方法論首先進行數據準備，然後進入數據挖掘階段，提出知識發現的概念體系和公認的apriori演算法，從該演算法演變出適合於貨代管理系統的生成頻繁項目集的演算法；因為在實際應用中存在效率上的不足，因此進一步地提出了改進方案；在事務處理中各個項目並不都是布爾型變量，因此需要特定的針對多值屬性的關聯規則發現演算法；通常情況下，項目之間存在有層次關系，因此多層次關聯規則的發現普遍存在；演算法完善並運行后需要對發現的知識進行解釋和評估；本章的最後討論了知識發現的私有性和安全性問題；第五章講述有待解決的問題和發展前景。
  12. Boolean comparisons are not case - sensitive ; other comparisons are case - sensitive

    。布爾型比較不區分大小寫；其他比較區分大小寫。

    是這種類型權限的一個示例，其狀態包含一些布爾型變量，這些變量表示執行不同操作的權限（如調用非託管代碼的權限） ，每一權限或者被允許，或者不被允許。
  14. The standard expansions of an arbitrary logic function in these complete sets from the rm, crm are deduced, and two examples are proposed to discuss the relation between the expansions in boolean subtraction - xor, division - coincidence algebraic systems and the expansions in and - or - not algebraic system

    舉例說明了與-或-非代數系統中規范中規范展開式與布爾減-異或、布爾除-符合代數系統中的規范展開式之間的轉換。
