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.

i have never been to troy, but david maule made me feel as if i were standing on the high wall of troy, watching the fierce war. thanks to this british author, who adapted the famous homer’s poem into a lively story, i found it easier to understand this story. though the story happened over 3000 years ago in a remote place, i was deeply fascinated by it.
the mysterious plot is one of the reasons why i loved the story of troy so much, yet i am more interested in the human heroes of the war.
hector was the eldest son of king of troy, priam. he was not only a real hero of trojan, but was regarded the highest moral hero in greek classic by later historians. the war started because of the mischief of his brother, paris, whom he didn’t appreciate. however, since hector was the commander of the trojan army, he was obliged to fight with all force. it was really a tragedy that such a valiant man died in the duel with another great warrior, achilles.
it is natural to see death in a war. as a famous chinese parable says, “a life can be as slight as a piece of feather, or as weighty as mount tai.” sometimes, one’s glory walks hand in hand with one’s doom. achilles was such a typical person. his personal charm made the story of troy more attractive. he was so crucial because his every appearance in a war encouraged his fellow soldiers and terrified the enemies. actually, achilles was half-god who was almost invincible in people’s mind. that’s why his name was memorized long after his death.
besides the two great men, the wisdom of odysseus also proved him to be a great hero. he didn’t want to attend the war because he was happily married and had a lovely son. however, since his country was allied to mycenae, he had to take the command given by the king of mycenae. i’m quite sure that the story of the wooden horse is widely known, however, few people know who thought of the brilliant idea, that’s why i admired odysseus so much because he was the person who got the idea. thanks to the horse, the ten-year war came to an end at last. if you want to know how the wooden horse worked, just read the book.
the ancient greeks believed that the gods and goddesses also played important roles in the origin, process and ending of the whole story.
the story of the golden apple was such an example. when eris, the goddess of argument and disagreement, threw out the golden apple to a wedding ceremony on mount olympus, a dispute happened. hera, the queen of gods, athena, the goddess of wisdom, and aphrodite, the goddess of love and beauty, were all involved in the argument for the apple. none of them was willing to give way, so they turned to paris for a final judgment. tempted by aphrodite’s beauty and promise, paris handed the apple to her. to keep her word, aphrodite helped him to get helen, the most beautiful woman in the world, as his wife. that was the cause of the war.
paris’s choice obviously annoyed the other two goddesses. so during the war, they helped the greek alliance army while some other gods, such as apollo and aphrodite, guarded troy. when paris dueled with helen’s former husband menelaus, aphrodite saved paris when he was about to be finished off.
after the duel between those two people, there was a truce between the greek alliance and troy. however, both hera and athena were not happy to see it. hera pursued her husband zeus:“ now, will you send athena to make the troyjans break the peace?”(page 22 then with zeus’s permission, athena went down to start the war again and finally she brought the greeks to success.
from the whole story, we can see that in ancient greeks’ view, gods sometimes played a much more important role in their life. however, with the rapid development of science, we have learned that the greek gods never existed. this is why a recent movie of troy has not mentioned a single god. everything happened due to men’s ambition, love, loyalty or jealousy. with those emotion and people’s effort, we human beings can accomplish wonders and be master of the world.
god are of less importance than they used to be. nonetheless, the gods and goddesses made the story of troy more mysterious and marvelous.
i have learnt from the book more than the wonderful story of history, love and war. i believe that human can determine their destiny by their own. i highly recommend this book to my friends.
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
