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
本文研究了web日誌挖掘中的相關技術,在以下幾方面進行了改進: ( 1 )在web日誌挖掘模型的基礎上,對web日誌數據的清洗和轉換提出了相應的解決方法; ( 2 )結合xml的優勢和web日誌數據的半結構化特點,提出用xml存儲日誌數據並探討了xml形式的日誌數據如何以中粒度方法實現在數據庫中存儲的方案; ( 3 )結合用戶訪問路徑的特點以apriori演算法為基礎提出了一種改進的挖掘頻繁訪問路徑的ufapa演算法,介紹了演算法思想及演算法描述。
