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.

Dear Mercy,
亲爱的梅斯，
How is everything going! Last time you said you are anxious now because you find it hard to learn English well. Don’t worry. I think you have to improve your English step by step. And I will right behind you. In my view, you should develop you interest on English first. According to my experience, I think watching English movie, listen to some wonderful English songs and talk in English on the Internet would be helpful. Secondly, you have to prepare lessons before class that will help you understand what the teacher says in the class. I know you feel bored in the class, but you have force yourself to be concentrated. A few days later you will feel it a little easy to learn English. The left steps I will tell next time. By the way, we have not seen each other since your family move to Hunan a year ago. Have you ever thought about going back to visit me and learn English together in the coming Summer vacation. Looking forward to your reply.
过得可好。上次你说你现在很焦虑因为你觉得很难学好英语。别担心。我觉得要提高英语你得一步步来。我会帮你的。在我看来，首先应该要培养你对英语的兴趣。根据我的经验，我认为看英文电影，听美妙的英文歌曲以及在互联网上与他人用英语交流会有很大的帮助。其次，你要预习，这样可以让你理解老师在课堂上说的东西。我知道你觉得上英语课很无聊，但你必须强迫自己聚精会神的听。一段时间后，你会感觉到学习英语变得容易些了。剩下的步骤下一次我会告诉你的。顺便提一下，自从一年前你们家搬到湖南后我们就没见过面。你有没有想过暑假的时候回来看看我，我们可以一起学习英语。期待你的回复。
Best wishes,
Li

2050年，一个全新的科技生活开始了，科技生活是什么样的呢?现在，就让我们一起去看看吧!
今天，我准备去参加一个朋友的生日party，展开随身携带的迷你、轻便、隐形的私家车，飞驶5分钟，便到了朋友家里。奇怪，在路上怎么没看到我的行踪?不要好奇，因为现在在宽阔的马路上，没有一辆汽车，只有自由自在的行走的路人，这是为什么呢?请你带上专门配制的眼镜，抬头看一看天空吧(注意，不要被吓坏了哦：天上全是汽车，真可谓是 “车山车海”啊!你一定会问;为什么那么多汽车，要带上专门配制的眼镜才能看得见呢?为什么车会飞起来呢?我来告诉你吧：为了不影响人们的生活，每辆车子上都配备了一双隐形的“翅膀”，只要按一下按钮，“翅膀”就会伸出来，升上天空自由行驶。那么，天空不就被废气污染吗?不会的，因为未来的汽车用的都是节能环保油，排出来的气体经过处理后都变成了空气净化气，这样空气不但不会被污染，还能得到更好的净化。汽车还配有道路帮助器，在你累了或不想驾驶时，只要按一下按钮，它就会蹦出一位驾驶员，你告诉他去哪儿，他就会驾驶到哪儿。这样就是再多的汽车也不用害怕会有环境污染、交通堵塞、交通事故或找不到路发愁了。
我家的家庭设施都是智能型的，按摩、做饭、打扫卫生、洗衣等等都由机器人来完成。你看，我刚从班上回来，感觉有些疲惫，按下按钮，就会出现一个机器人，按我的需求帮我按摩，有感情地读书给我听，消除我的疲劳。我感觉饿了，再按下按钮，不到三分钟，可口的饭菜就端上来了。我的家里永远都是一尘不染，让人赏心悦目的，这些都是由人性化的机器人来完成的，它可以按照我的要求整理好房间，打扫好卫生......
未来的笔就更独特了。你看，在我用它写作业时，如果写错了，它就会自动帮助我把写错的字擦去或打上标记，让我重新写，如果又写错了，它就引导我的思路，让我做出正确的答案。而且它的笔芯永远不会用完，它会不断地产生，让我不用为笔坏了或没笔芯了烦神。最重要的一点是它可以改掉我做作业时的很多坏毛病，比如写字马虎了，它就纠正我的不认真态度;做作业走神了，它就用它的独特方式引导我;做作业粗心了，它就强化我的作业正确率……所以用这样的笔做我的好帮手，可以让我做作业效率不断提高，而且成绩越来越好!
未来的科技生活真是太奇特了，让我们以把这么美的科技生活作为发奋的目标，向着这个目标努力吧!
