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.

（一）概念：
排比是由三个或三个以上结构相同或相似、内容相关、证据一致的短语或句子排列在一起，用来加强语势强调内容，加重感情的修辞方式。
（二）排比和种类：
１、成分排比 即一个句子中的一些成分组成排比。例如：
延安的歌声 它是黑夜的火把，雪天的煤炭，大旱的甘霖。
２、分句排比 即一个复句的各个分句构成排比。例如：
他们的品质是那样的清洁和高尚，他们的意志是那样的坚韧和刚强，他们的气质是那样的淳朴和谦逊，他们的胸怀是那样的美丽和宽广。
３、单句排比 例如：
八路军穿草鞋，把日本鬼子赶下海。解放军穿草鞋，把蒋家王朝踢下台。如今八连穿草鞋，把香风毒雾肢下踩。
４、复句排比。例如：
如果我们能够研制出一种类似 鹰眼的搜索、观测技术系统，就能够扩大飞行员的视野，提高他们的视敏度。如果能研制出具有鹰眼视觉原理的“电子鹰眼”，就有可能用于控制远程激光制导武器的发射。如果能给导弹装上小巧的“鹰眼系统”，那么它就可以象雄鹰一样，自动寻找、识别、追踪目标，做到百发百中。
（三）排比的作用：
１、内容集中，增强气势；２、叙事透辟，条分缕析；３、节奏鲜明，长于抒情。
（四）排比与对偶的区别：
１、对称性与平列式。对偶是二个语言单位，而排比是三个以上语言单位。对偶必须对称。排比要求结构大体相似，字数要求不甚严格。
２、排比经常以同一词语作为彼此的揭示语，使排体互相衔接、给人以紧凑、密集之感。而典型的对偶句上下两联是不重字的。
３、对偶以要求平仄对仗为佳，排比则无此要求。
