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。 -
We also place emphasis on research of apriori and fp - growth algorithm and compare the performance of two algorithms. secondly, we do research on concepts of structured and nonstructured data, actual state and problems of tree structure mining, and freetreeminer algorithm theory. we also study canonical form and pre - processing technologies of free - tree, concepts and properties of closed and maximal tree, and pruning, growing and mining of tree structure
其次，研究了結構化與非結構化數據的基本概念、樹結構挖掘的研究現狀、現有樹結構挖掘技術存在的問題、 freetreeminer演算法及其基本思想，重點研究了free樹的規范化和預處理技術、封閉頻繁子樹和最大頻繁子樹的概念和性質、樹結構的剪枝和生長技術、樹結構的挖掘技術。
