yes,there is really something it the letter.
I am always wanting to find a decent background for my thesis, but in vain:(
maybe I should follow the opinion in the letter.

【 在 yaomc (白头翁&山东大汉) 的大作中提到: 】
: Hi,
: I have something to say about data which can be used in research. 
: Actually there are lots of benchmark datasets online. You can search 
: through Google; or if you are interested particularly in an algorithm, 
: you can even ask for dataset from the authors of the relevant paper. 
: Generally they would like to provide the dataset they used for your 
: further studying, experiments and research. 
: After getting the data sets, I asure some people will argue that these 
: kind of data are not that of large scale or don't have some other 
: characteristics. While some will argue that they don't know the domain 
: knowledge about the data, how can they do research with it. Actually 
: it is very common to think in this way, I myself also experienced this 
: stage. Sooner or later, you will find that whether the data is perfect 
: is not important; instead, the key point is to play with the data in a 
: systematical way. You can play with data at a very abstract level, say,
:  you know nothing about the background; you can change the data set a 
: little bit, and see how the performance of the algorith will change; you
:  can apply the same algorithm, say Aprior, to the market basket data, or
:  you can apply it to the website log file data... These are just a few 
: examples.
