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.

绿川幸是我最喜爱的日本漫画家之一。他的漫画作品大多以短篇为主，构思巧妙，因而拥有众多漫迷。
Through her works， my favorite one is Xiamuyourenzhang.
在她的作品中我最喜爱的一部是《夏目友人帐》。
The comic book mainly talks about that the hero Xiamuguizhi has a special ability to see the bogies. He is unsociable because his parents are dead. And he often lives in his relatives' home when he is a little boy and his friends at his age always tease him because he has a special ability. Although he experiences many unfortunate things, he is still very kind and without complaint at anyone. Eventually he is adopted by a couple who is very friendly and let him go to high school. One day, He is pursued by a bogie and hid in a shrine. He breaks a powerful bogie‘s seal whose name is Ban. And that involves her grandmother Xiamulingzi’s relics--a contract that sigh with the bogies. Since then, this powerful bogie turns itself into a cat in daily life to stay with Xiamu to protect him with the condition that Xiamu should give the contract to it after he die. But before that Xiamu decides to try his best to give the name in the contracts to the bogies and let them get free. Thus, a loving, touching, scary story is opened up.
《夏目友人帐》主要讲述了男主人公夏目贵志拥有可以看到妖怪的特殊能力。因为父母双亡他的性格较为孤僻，并且由于他具有特殊的能力，他常辗转在于亲戚之间并被同龄人欺负。虽然他经历了许多不幸，但他依旧有好善良没有埋怨任何人。最终他被有好善良的藤原夫妇收养并进入高中。有一天，他被妖怪追赶躲进神社，不小心打破了一只强大妖怪斑的封印。并牵涉到了他祖母夏目玲子的'遗物—一本同妖怪签订的契约书。之后，这只强大的妖怪平时便变成猫的样子待在夏目身边保护他，但是他的条件是夏目后要把这本契约书给它。但在此之前夏目决定尽其所能把契约书上的名字还给妖怪们让它们得到自由。由此，一个个温馨、感人、惊险的故事就此展开。
In addition, yuki midorikawa has another special work called Yinghuozhisen is also really moving ，sad and beautiful. I suggest that you all can watch it when you have free time.
此外，绿川幸的另一部作品《萤火之森》同样十分治愈感人建议大家有空可以看看。
