——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.
《notre dame cathedral》 is one known far and wide romantic faction strength which victor hugo writes . i take advantage of this summer vacation free time, read this great work.
notre dame cathedral's story, actually was one at that time social epic poem, since brimmed with really. friendly. beautiful, also the flow selfish desire and is false. regardless of is good beautiful asmelada ,or has the ugly semblance, cacimodo with one pure mind, they represent the great amount the lower level populace which suppresses; perhaps is sinister coloud, he is appears by the theocracy face, all load bearing one kind of author's ponder.the author in this work, for with the clown, was beautifully friendly and wickedly does the best annotation, or take above three people as the example, the rebel asmelada has the beautiful semblance and the chaste good mind, as well as pitiful destiny, but cacimodo, he withstood destiny deceive nicely, the innermost feelings is his misery is graver, but coloud maintained the benighted social rights and interests, he had brutally. void mind and evil passion. good person physique hateful, but the evil person actually says the appearance shore however, bright set off, social unfair manifest.
but the article result also is when the opposition society until criticism: all beautiful is good all swallows by the might and the evil, the lower level people's weak strength in under the king power rule, in the benighted society, only can be reduced to ashes. was palatial notre dame cathedral, how many world tragedy testimony once, in hugo the novel, he as if had the life breath, he sheltered asmelada ,exposed coloud the crime, regret the populace attack the magnificent feat which dark actually heroically devoted...
another the question which is worth pondering is: who is the hero? asmelada or cacimodo? i think all is not, but is in the article by the louis 11 rank smell of blood suppression rather for sacreficed the populace gate, asmelada with cacimodo is not in them the representative, asmelada is loves with the beautiful symbol, cacimodo not many represents is unfortunate and the pain. but they, all suffer a tragic middle ages ignorant evil forces devastate, one each one painful soul is bleeding, flows the tear. merely is notre dame cathedral's above engraves " the destiny "? they are in middle ages france, despotism sacrificial victim.
the entire story rich tragic color, the plot intense is moving, exciting. author hugo through " notre dame cathedral " this story, but also disclosed at that time the dark society's essence to the people. this fascinating story likes that ccimodo clocks sound equally shocks several generation of readers' minds.
