-------reading after a science paper

these daysi am busy preparing my diertation which is about web usage mining.i read some english papers and learnt much from them.and nowi want to say something about a paper titled “web usage mining ：discovery and applications of usage patterns from web data”.this is the first english paper i read about diertation and gave me great help.this paper is a review about web usage mining.it introduced web usage mining in detail.although it is a little old for it was published in XXits contents are very useful today.it is organized according to the sequence of web usage mining and the six main parts are introduction which tells me what is web usage miningthe sources and abstraction of web datathe three steps of web usage miningtaxonomy and project surveywebsift overviewprivacy iues.the third and fourth parts are most important.it had a list of existing project about web usage mining which i saw many times in other papersbut this paper is the one creating this list.besidesit has been referred for more then twenty times.as we all know thatthe higher the referred number isthe more important the paper io i consider this paper to be an important and succeful one in this region.in my opinionthe succe of this paper dues to three reasons.the first reason is the profound computer knowledge owned by the authors.web usage mining relates to many subjectuch as artificial intelligenceontologysemantic analysisbut the most basic knowledge is computer science.the four authors are all profeors of department of computer science and engineering in university of minnesota.for myselfi am not major in computer science and i am not very good at computero i feel a little difficult to understand technologies used in this region.secondthey had read a large number of papers before they wrote this paper.there are fifty nine references listed after main contents.“stand on the shoulders of giants”this sentence tell us a truth : one can never succeful all by oneself.and what’s morelearn from others can save a lot of time and energyespecially for us new learner.how to learn from others is a skill all of us should masterbut learning doesn’t mean copy or plagiary.other people’s knowledge and production is just our foundationupon this foundationwe must have our own thoughts and creation.there are many remarks in this paper where referred other’s production.thirdthe authors had the experience of developing a web usage mining project.they don’t just engage in idle theorizingso their comprehension on this iue is greatly profound.they know what we may meet in a real project development and they know how to resolve them.after reading this paperi also read some other papers written in chinese.some of them are not based on real project and can not give useful resolution.websift is the name of system they developed which can be used to data mining and analysis.
