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.
当新学期来临时,许多学生对新生活表现得很兴奋。在大学,新生快乐地享受着自由。在接下来的四年里,他们希望过着高中描绘的'美好生活。但事实是,大学生活中有很多东西要学。
First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.
首先,专业知识占据着最重要的角色。作为一名学生,学习知识是他们的工作,而很多学生在课堂上玩手机,或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力,可悲的是,大多数人没有意识到这一点。
Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.
第二,由于空闲时间多,他们可以充分利用好这些时间,并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好,或找份兼职工作。比呆在宿舍玩电脑游戏好多了。
A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.
很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。
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.
在英语村里,模拟了现实生活中的四个场景——“城市馆”、“自然馆”、“生活馆”和“商业馆”,四个场馆中的部分物品和布景都是实物,每个场馆又被分成几个场景,外教和中教轮流授课,我们这次可真是与英语世界来了个亲密接触。在全英语的语言环境和实物情境下,我们对学习英语的兴趣变得前所未有的高涨。就比如说在城市馆里吧,刚进城市馆,一个美丽的大都市——上海的模型立刻呈现在我们的面前,那一个个地标性建筑物的模型,在镭射灯光的映衬下是显得格外的雄伟壮丽,你甚至猜想不到的是在城市馆里居然会有一节能移动的地铁车厢,在最后一节课中,老师终于带着我们“乘坐”了一次地铁,这“地铁”中,老师不停的作者令人捧腹的`动作,使得大家都争先恐后的想“乘坐”一次平时已经坐得习以为常的地铁。每当外教拉开悬挂的粉红色幕布时,或旋转布景板进行场景切换时,我们都会发出声声惊叹,因为,我们以前从来没有这样学习过英语。在商业馆的超市里,甚至可以看到真实的收银机等等实物,我们真实地体验着用英语对话来购物的整个流程,我们扮演着不同的角色,来学习这个角色所要说得话;在生活馆里,老师会用英语生动地为我们介绍各式厨具用品,并且还和我们做游戏,让我们在游戏当中来巩固与加深你对这个英语单词的印象,如果你读得好的话,老师会和你拍手,表示鼓励;在自然馆中,我们仿佛亲身来到了大自然中,有热带雨林,有北极,海洋,在教室的墙上还贴着国家的地图和标着英语单词的国旗名称,在自然馆中最有趣的还是要数在进门时有一座假山,不高的假山上悬挂着一个吊绳,仿佛可以真的用来攀岩一般。我们不时为老师们幽默、生动的语言、表情和肢体动作爆发出阵阵笑声,为同学的精彩表现鼓掌加油。
通过这次活动,让我们在现实生活中快乐的学习了一次英语,也然我的英语水平提高了不少,希望以后这样的实践活动多一些,能够我们丰富我们的课外生活。我期待着有更多的同学能来到这个英语村里来,让他们也体验到更多学习英语的快乐!
