Dear Dr. Ruifeng Xu,

For my research I designed a review corpus (for text-based sentiment classification). UTF-8, simplified Chinese. You can find two versions of it on http://www.informatics.sussex.ac.uk/users/tz21/

it168test - the corpus consists of 2317 reviews of mobile phones of which 1158 are negative and 1159 are positive (more info in a readmr.txt file inside).

coling08 - the corpus consists of 10 subcorpora containing a total of 7982 reviews, distributed between 10 product types (more info in a readmr.txt file inside).

Hope you can find them useful.

Best regards, Taras Zagibalov
