Web Data Mining For Real-time Information Based On XML

Since Internet came into being, the information in it has increased so rapidly by exponent. How to find and get the useful info has already been a hotspot in Data Mining, then Web Data Mining emerged as the times require.Web is an information warehouse which is huge, widly distributed, highly isomerous, hyper text and hyper media, while including abundant, dynamic hyperlink and visitorial, usage information to web pages. Because nowadays network environment is based on HTML which only describes forms rather than discovers content, so the problems of half or non-structure datum and isomerous database source bring difficulties for web data mining. XML (Extensible Markup Language) which is developed by W3C supports abundant data structure, especially emphasizes the relationship between semantics and element, so web data mining based on XML can make full use of XML characteristic, and brings new chance.Firstly, the paper expatiates on the methods of web data mining based...
