Topic modeling in chinese

[Thibault Maillard]

Hello,

I am a student in chinese study. My chinese is not too bad but not good enough to write you in chinese and also find what I want for now.

I would like to do some topic modeling on a database of articles in chinese using R.

Is there a tutorial for that? I have found topic modeling tutorial for english but I could not find it for chinese.

The keyword function of jiebaR indicates the frequency of the most common word? How can I check if a term is part of the jiebaR dictionnary?

And last thing, I would like to check if an article or group of article is more positive or negative, how can I do that?

Thank you very much!

T.M.
