——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.
i have never been to troy, but david maule made me feel as if i were standing on the high wall of troy, watching the fierce war. thanks to this british author, who adapted the famous homer’s poem into a lively story, i found it easier to understand this story. though the story happened over 3000 years ago in a remote place, i was deeply fascinated by it.
the mysterious plot is one of the reasons why i loved the story of troy so much, yet i am more interested in the human heroes of the war.
hector was the eldest son of king of troy, priam. he was not only a real hero of trojan, but was regarded the highest moral hero in greek classic by later historians. the war started because of the mischief of his brother, paris, whom he didn’t appreciate. however, since hector was the commander of the trojan army, he was obliged to fight with all force. it was really a tragedy that such a valiant man died in the duel with another great warrior, achilles.
it is natural to see death in a war. as a famous chinese parable says, “a life can be as slight as a piece of feather, or as weighty as mount tai.” sometimes, one’s glory walks hand in hand with one’s doom. achilles was such a typical person. his personal charm made the story of troy more attractive. he was so crucial because his every appearance in a war encouraged his fellow soldiers and terrified the enemies. actually, achilles was half-god who was almost invincible in people’s mind. that’s why his name was memorized long after his death.
besides the two great men, the wisdom of odysseus also proved him to be a great hero. he didn’t want to attend the war because he was happily married and had a lovely son. however, since his country was allied to mycenae, he had to take the command given by the king of mycenae. i’m quite sure that the story of the wooden horse is widely known, however, few people know who thought of the brilliant idea, that’s why i admired odysseus so much because he was the person who got the idea. thanks to the horse, the ten-year war came to an end at last. if you want to know how the wooden horse worked, just read the book.
the ancient greeks believed that the gods and goddesses also played important roles in the origin, process and ending of the whole story.
the story of the golden apple was such an example. when eris, the goddess of argument and disagreement, threw out the golden apple to a wedding ceremony on mount olympus, a dispute happened. hera, the queen of gods, athena, the goddess of wisdom, and aphrodite, the goddess of love and beauty, were all involved in the argument for the apple. none of them was willing to give way, so they turned to paris for a final judgment. tempted by aphrodite’s beauty and promise, paris handed the apple to her. to keep her word, aphrodite helped him to get helen, the most beautiful woman in the world, as his wife. that was the cause of the war.
paris’s choice obviously annoyed the other two goddesses. so during the war, they helped the greek alliance army while some other gods, such as apollo and aphrodite, guarded troy. when paris dueled with helen’s former husband menelaus, aphrodite saved paris when he was about to be finished off.
after the duel between those two people, there was a truce between the greek alliance and troy. however, both hera and athena were not happy to see it. hera pursued her husband zeus:“ now, will you send athena to make the troyjans break the peace?”(page 22 then with zeus’s permission, athena went down to start the war again and finally she brought the greeks to success.
from the whole story, we can see that in ancient greeks’ view, gods sometimes played a much more important role in their life. however, with the rapid development of science, we have learned that the greek gods never existed. this is why a recent movie of troy has not mentioned a single god. everything happened due to men’s ambition, love, loyalty or jealousy. with those emotion and people’s effort, we human beings can accomplish wonders and be master of the world.
god are of less importance than they used to be. nonetheless, the gods and goddesses made the story of troy more mysterious and marvelous.
i have learnt from the book more than the wonderful story of history, love and war. i believe that human can determine their destiny by their own. i highly recommend this book to my friends.

《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.
