Based on integration of " high yield & benefit and good grain quality of modeled cultivation of foodstuff crop ( rice ) and its consultation system ", this thesis sets it ultimate goal to deal with the knowledge discovery in the consultation system of simulation - optimization decision making in quality and high - yielding rice cultivation. after a close study of the features of the database in rice cultivation, this thesis introduces the system engineering theory of agent aralysing and designing and offers a practical new way to promote the intelligence of the knowledge discovery system in rice cultivation database, to improve the efficiency of data mining and the human - computer interactive ability to realize the integrated knowledge - based combination between human and computer or among the sub - systems
本文以廣西「糧食作物（水稻）兩高一優模式栽培技術集成與咨詢系統研究」為背景，以基於專家系統（ es ）的水稻優質高產栽培模擬優化決策咨詢系統的知識獲取問題為導向，針對水稻栽培數據庫的特點，從系統工程角度引入面向agent的分析與設計思想，提出一種用多agent從水稻栽培數據庫中發現知識的人機合作、半自動的知識獲取方法，實現利用多agent的自主性、反應性和社會性，提高水稻栽培數據庫知識發現系統的智能水平、數據挖掘效率和人機交互能力，實現人機之間、各子系統之間基於知識的柔性綜合集成，為水稻栽培知識發現提供了一條新的可行途徑。The paper is about how to analyze web server ' s log file and the technology used and tries to improve it in the following aspects : ( l ) this paper presents a simple processing model on mining web log based on xml storage and the corresponding solutions used to clean and transform log data. ( 2 ) according to the advantages of xml and the self - structure feature of log data, the paper proposes the novel idea that stores log data in xml form, furthermore it discusses the method and implementation on how to store xml - compliant log data into the database by the medium - grained storage means. ( 3 ) this paper addresses an improved algorithm called ufapa for mining user frequent access path on the basis of the algorithm apriori
