——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.

尽管专家、老师都鼓励孩子建立错题本，孩子也意识到它的重要性，但是一到实际建立的时候就很难坚持，甚至建了错题本也不能很好地使用。有学生说：“主要是抄写题目比较麻烦，尤其是比较长的题目，感觉特别浪费时间。爸爸妈妈都很忙，也没有太多时间帮我抄。”还有学生说：“错题倒是记录下来了，可是由于没有进行分类整理，面对一大堆错题感到非常茫然，不知如何下手。”
深圳实验学校的一名成绩优秀的学生告诉记者，他有一个秘密武器——那就是“习网网络错题本”。这种网络错题本拥有大量的习题、试卷和资料，完全不需要抄写题目，根据自主测试结果错误的'题目会自动纳入到“错题本”，还可以针对错题进行举一反三的错题训练，非常好用，现在全班同学都在用。
记者针对这种网络错题本进行了考察，发现它具有以下几个优势：一是错题来源于孩子网上的作业和自主测试，可以省去抄写题目的麻烦，节约时间；二是系统会根据知识点错误从题库中抽取相应题目进行强化训练，达到消除错题的目的；三是系统提醒孩子进行错题分类和错误分析，能够帮助孩子有效地使用错题本。记者发现，网络错题本符合无纸化环保的理念，能够得到教育相关部门的支持，成为一种流行趋势。
