how to do research
——reading after a science paper
these days i am busy preparing my dissertation which is about web usage mining . i read some english papers and learnt much from them . and now i 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 dissertation 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 its 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 mining the sources and abstraction of web data the three steps of web usage mining taxonomy and project survey websift overview privacy issues . 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 papers but this paper is the one creating this list . besides it has been referred for more then twenty times . as we all know that the higher the referred number is the more important the paper is so i consider this paper to be an important and successful one in this region.
in my opinion the success 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 subjects such as artificial intelligence ontology semantic analysis but the most basic knowledge is computer science . the four authors are all professors of department of computer science and engineering in university of minnesota . for myself i am not major in computer science and i am not very good at computers so i feel a little difficult to understand technologies used in this region.
second they 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 successful all by oneself . and what’s more learn from others can save a lot of time and energy especially for us new learner . how to learn from others is a skill all of us should master but learning doesn’t mean copy or plagiary . other people’s knowledge and production is just our foundation upon this foundation we must have our own thoughts and creation. there are many remarks in this paper where referred other’s production.
third the authors had the experience of developing a web usage mining project . they don’t just engage in idle theorizing so their comprehension on this issue is greatly profound. they know what we may meet in a real project development and they know how to resolve them . after reading this paper i 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 .
i wrote this article not only because it gave me much help in preparing my dissertation but also because it tells me how to study and how to do research . honesty and preciseness are two essential making a researcher must have . hard-working is the necessary condition leading to success . this is just the beginning of my dissertation i should learn from these four authors both their knowledge and their attitude to study.
您好!
您知道吗?每当我走过语音室时,总会透过明净的玻璃窗去看看里面的设备,语音室里的一切对于我来说都是那么新奇,那么吸引人。跟着您,在高科技设备装配的语音室里学英语,是我当时最大的愿望。可是,自语音室建好以来,您从未带同学们进去参观过,更没带同学们进去上过一节课,这使得我的愿望变得那样渺茫。
王老师,记得您每次在我们教室里上课时,起码有三分之一的同学在小声说笑,因此,教室里总是乱哄哄的`,可您却很少制止。王老师,维持课堂秩序是您的职责呀,您为什么不去制止他们?还有,您每次提问学生时,一旦同学回答不上来,您总会露出一副不耐烦的神情,为此,许多同学感到很伤心,好多同学也不喜欢上您的课。
王老师,学校培育了我五年,我希望学校越办越好,希望老师能教得开心,我们也能学得开心。因此,我诚心诚意地给您提几条建议,希望您能采纳。
一、每周带同学们到语音室上一次英语课。
二、您不要不管那些上课小声说笑的同学。作为一名教师,您有责任对他们进行批评和教育。
三、今后,请您对那些回答不上问题的同学多一些宽容和理解,并耐心地讲解,这些同学会非常感激您的,他们也会越来越喜欢您的。
王老师,如果您能采纳我的建议,我将十分开心。我坚信您一定会成为我们心中的好老师!
祝您工作顺利!
您的学生:张辉君

《notre dame cathedral》 is one known far and wide romantic faction strength which victor hugo writes . i take advantage of this summer vacation free time, read this great work.
notre dame cathedral\'s story, actually was one at that time social epic poem, since brimmed with really. friendly. beautiful, also the flow selfish desire and is false. regardless of is good beautiful asmelada ,or has the ugly semblance, cacimodo with one pure mind, they represent the great amount the lower level populace which suppresses; perhaps is sinister coloud, he is appears by the theocracy face, all load bearing one kind of author\'s ponder.the author in this work, for with the clown, was beautifully friendly and wickedly does the best annotation, or take above three people as the example, the rebel asmelada has the beautiful semblance and the chaste good mind, as well as pitiful destiny, but cacimodo, he withstood destiny deceive nicely, the innermost feelings is his misery is graver, but coloud maintained the benighted social rights and interests, he had brutally. void mind and evil passion. good person physique hateful, but the evil person actually says the appearance shore however, bright set off, social unfair manifest.
but the article result also is when the opposition society until criticism: all beautiful is good all swallows by the might and the evil, the lower level people\'s weak strength in under the king power rule, in the benighted society, only can be reduced to ashes. was palatial notre dame cathedral, how many world tragedy testimony once, in hugo the novel, he as if had the life breath, he sheltered asmelada ,exposed coloud the crime, regret the populace attack the magnificent feat which dark actually heroically devoted...
another the question which is worth pondering is: who is the hero? asmelada or cacimodo? i think all is not, but is in the article by the louis 11 rank smell of blood suppression rather for sacreficed the populace gate, asmelada with cacimodo is not in them the representative, asmelada is loves with the beautiful symbol, cacimodo not many represents is unfortunate and the pain. but they, all suffer a tragic middle ages ignorant evil forces devastate, one each one painful soul is bleeding, flows the tear. merely is notre dame cathedral\'s above engraves \" the destiny \"? they are in middle ages france, despotism sacrificial victim.
the entire story rich tragic color, the plot intense is moving, exciting. author hugo through \" notre dame cathedral \" this story, but also disclosed at that time the dark society\'s essence to the people. this fascinating story likes that ccimodo clocks sound equally shocks several generation of readers\' minds.

a tale of two cities occupies a central place in the canon of charles dickens\'s works. this novel of the french revolution was originally serialized in the author\'s own periodical all the year round. weekly publication of chapters 1-3 of book 1 began on april 30, 1859. in an innovative move, dickens simultaneously released installments of the novel on a monthly basis, beginning with all of book 1 in june and concluding with the last eight chapters of book 3 in december. dickens took advantage of the novel\'s serial publication to experiment with characterization, plot, and theme. he described the work in a letter to his friend john forster, cited in rudi glancy\'s a tale of two cities: dickens\'s revolutionary novel, as \"a picturesque story rising in every chapter, with characters true to nature, but whom the story should express more than they should express themselves by dialogue.\" the novel that emerged from his experimentation is now regarded as one of dickens\'s most popular and most innovative works.
dickens\'s work was very popular with the reading public when it was first published. one review in the magazine athenaeum stated that a tale of two cities had attracted the praise of a hundred thousand readers. on the other hand, a whole set of critics, most notably sir james fitzjames stephen writing in saturday review, criticized the novel precisely for its popularity. \"most of the critics writing in the intellectual and literary journals of the day considered popular success a good reason to condemn a work,\" explains glancy. \"if the public liked it, they certainly could not be seen to approve of it at all.\" modern critical opinion, however, has given the novel an important place among dickens\'s most mature works of fiction.
