  3. The reasoning of structured model : how to transfer structured model into mathematical model that can be solved by an arithmetic system ; the determination of the most appropriate target case includes two steps : the first is wide retrieval, and the second is extract retrieval that is a method driven by adaptation rules. the case base maintenance : case storage and case knowledge maintenance. the last part of this paper is about the real information system, which introduces the analysis and design of the information system and uses a real case to describe how the system operates

    這些研究工作包括：事例和問題的知識表示：給出屬性集、結構集和目標集的事例表示方法；知識化模型的推理：結構化的模型如何轉化為求解系統可識別的屬性模型的過程；最相似事例的確定：兩步選擇過程，粗選過程按屬性相交度，精選按類比轉換的規則驅動的確定最相似事例的原則和方法；類比轉換的方法：確定在一定條件下的轉換方法；事例庫的維護：事例庫是可維護的，一方面隨著系統解決問題的增多，事例庫也會不斷擴大知識領域；另一方面，通過事例庫維護模塊，可以從用戶那裡得到新的建模知識。
  4. Some problems about the maintenance of the knowledge base in expert system

    專家系統中知識庫維護的若干問題
  5. These methods are flexible in use. this thesis gives a system of defects sorting and a flow of defects reasoning and analyzing on physical field. by building a knowledge - base, a reasoning mechanism, a explaining mechanism and a defects information coding, the defects analysis system integrate defects information and defects analysis function, which include defects inquire, defects causes analysis, measure & suggestion of defects preventing and knowledge - base maintenance

    本文提出了按物理場的缺陷分類體系和缺陷推理分析流程，並通過建立知識庫、推理機制、解釋機制和缺陷信息編碼，系統基本實現了缺陷查詢、缺陷原因分析、缺陷防止措施與建議和知識庫維護等功能和缺陷信息的集成。
  6. The specialties of the system are personalization, self - determination, maintenance web information and knowledge - base, collaboration, expansibility and so on

    系統具有以下特點：個性化、自主性、信息維護功能和知識維護功能、協作性、擴充性等。
  7. According to the trouble information, the concrete trouble type is judged by using the mixed systematic knowledge base on the symptom fact database, traditional expertise experiences diagnosis rule and data mining. and the diagnosis conclusion and maintenance information are displayed on the remote customer browser

    利用基於徵兆事實庫、傳統專家經驗診斷規則和數據挖掘診斷規則的混合系統知識庫，根據故障信息判斷出具體的故障類型，並將診斷結論和維護參考信息顯示在遠端客戶瀏覽器上。
  8. The main reasons are as follows : firstly, the knowledge in knowledge base is not able to meet the needs of the system, because on the one hand, it is impossible and unrealistic to make it all - inclusive, and on the other hand, the representation of knowledge also restricts the functions of the systems ; secondly, though many intelligent instructional systems have been developed, seldom knowledge bases were designed utilizing method of knowledge engineering, which certainly affected the management, retrieving and sharing of the knowledge, and thus the maintenance and expansion of the systems

    主要原因有：一是，知識庫中的知識不能滿足系統的需要，因為要想使知識庫的知識包羅萬象，是不可能的，也是不現實的；同時，知識的表示也制約了系統的功能。二是，盡管開發了許多智能化教學系統，但很少用知識工程的方法設計知識庫。這樣勢必影響知識的管理、獲取和共享，從而影響系統的維護和擴充。
  9. In chapter four, based on the analysis and comparison of the three ways of knowledge expression, we put forward the knowledge expression method of this spc expert system. in this chapter, the management and maintenance of the knowledge base is discussed
