[R] data mining/text mining?

[Weiwei Shi]

Dear Ruixin:
Among others, text mining is dealing with non-structural data while
data mining mainly focuses on structural one. Many algorithms can be
shared b/w them; however, some necessary data preprocessing is
required for text mining. There are a lot of online-resource there.

As to packages used for text mining in R, esp. for preprocessing,
please check the following link:
http://wwwpeople.unil.ch/jean-pierre.mueller/

I used that package very long time ago and am not sure if they are
updated for this current version of R; otherwise, you might need to go
back the old version like R1.1.

If you want to do text mining for chinese text (I guess :), there is
additional work (i.e. word splitting) needed. I remember there is some
researcher from Taiwan who does pretty good work and you can google
that. I cannot remember the details.

HTH,

Weiwei
