其他范文/读书笔记 英语读书笔记 yesterday i read a book the name of the book isdr bethune.dr bethune was a famous doctor from canada. in 1938 he came to china. at that time china was at war with japan. he worked as a doctor in the chinese army and saved many soldiers lives. he worked very hard and became sick. dr bethune died in 1939. he was only 49 years old. he was a good man and we remember him today.i think the book is very very good!written by wu qingxiangmar. 31XXhow 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 XX 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 whats 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 doesnt mean copy or plagiary . other peoples 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 others production. third the authors had the experience of developing a web usage mining project . they dont 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 .
