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.
我们六一班的英语老师有20岁左右。她有一头乌黑油亮的头发,淡淡的眉毛下有一双水汪汪的大眼睛。然而,她双眼中间的鼻梁却是塌的,她一脸的冷酷与那张樱桃小嘴显得很不协调。
还记得开学第一天,本来喊着“欢迎老师”的同学霎时停了下来。一位年轻老师走到讲台中间转过身来,板着脸严肃地说道:“以后你们的英语课由我来上。”霎时,教室里突然静得出奇。同学都被这冷冰冰的一句话给吓“傻”了,呆呆地坐着,眼睛瞪得比木槌还直。之后的半个小时她都在“训斥”我们:“……要是有同学说话——没商量,我就用杆子抽他!要是我听说有人在背后骂我,你就给我等着……”下课后,每个同学都不由自主地打了个寒颤。
接下来的日子里,英语老师下课拖堂、“非法”占用微机课和体育课、作业量布置太大。这些“罪行”使同学们对她没有一丝好感。
一天,英语老师用英语讲了一整节课,同学们就叫她“放臭洋屁的”,得知英语老师写字要用卫生纸包着粉笔写,她的外号就成了“死臭美的”。
终于有一天,周侠宇同学被老师罚写14遍英文加14遍译文,他背地里对英语老师狠狠地骂了一顿,并在楼梯的墙壁上刻下了骂英语老师的脏话。这件事很快就被英语老师知道了。英语老师就像只暴怒的狮子,她的举动让大家都惊呆了。只见她从教室里将周侠宇“揪”出来,然后就对他大打出手。五分钟后,周侠宇就被带进了英语办公室。又一阵拳打脚踢过后,英语老师就开始了她的“长篇小说:“……你说说你该罚吗?你真是无耻!你还有良心吗?不想学趁早滚蛋……”在窗外偷看的同学早已看不下去了,都想进去找英语老师理论理论。
我永远也忘不了英语老师那张“凶神恶煞”的脸,但我多么希望英语老师能够和蔼一些,经常笑笑,给下一个班的同学们留下一个好的印象。
《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.
