　　-------reading after a science pa-pe-r

　　these days , i am busy preparing my dissertation which is about web usage mining . i read some english pa-pe-rs and learnt much from them . and now , i want to say something about a pa-pe-r titled “web usage mining ：discovery and applications of usage patterns from web data”.

　　this is the first english pa-pe-r i read about dissertation and gave me great help .

　　this pa-pe-r 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 pa-pe-rs , but this pa-pe-r 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 pa-pe-r is , so i consider this pa-pe-r to be an important and successful one in this region.

　　in my opinion , the succeof this pa-pe-r 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.
