A brief introduction to data mining in e - commerce 淺說電子商務中的數(shù)據(jù)挖掘技術
Based on the introduction to data mining , text mining andknowledge management , we divide the knowledge management into three phases , knowledge repository , knowledge sharing and knowledge discovery respectively , from the view - point of technical development . we analyse the key component of text mining , and point out that it is the main trend of intelligent information processing in the coming new century 本文首先介紹了數(shù)據(jù)挖掘、文本挖掘和知識管理等概念,然后從技術角度出發(fā),將知識管理劃分為知識庫、知識共享和知識發(fā)現(xiàn)三個階段,分析了作為最高階段的知識發(fā)現(xiàn)的關鍵技術和意義,最后指出在文本中進行知識發(fā)現(xiàn)是新世紀智能信息處理的重要方向。
Data mining always faces complicated tasks that including classification , prediction , association rule discovering and clustering , etc . in the first part of this paper , we give brief introduction to data mining and its relation with data warehouse and olap ( online analytical processing ) technology 數(shù)據(jù)挖掘面對的任務是復雜的,通常包括分類、預測、關聯(lián)規(guī)則發(fā)現(xiàn)和聚類分析等。在本文中,我們先介紹了數(shù)據(jù)挖掘的基本概念及其和數(shù)據(jù)倉庫、 olap (聯(lián)機分析處理)的關系。
