The words that people use could reveal their emotional states, inten-tions, thinking styles, individual differences, etc. LIWC (Linguistic Inquiry and Word Count) has been widely used for psychological text analysis, and its dic-tionary is the core. The Traditional Chinese version of LIWC dictionary has been released, which is a translation of LIWC English dictionary. However, Simplified Chinese which is the world's most widely used language has subtle differences with Traditional Chinese. Furthermore, both English LIWC dictio-nary and Traditional Chinese version dictionary were both developed for rela-tively formal text. Microblog has become more and more popular in China no-wadays. Original LIWC dictionaries take less consideration on microblog popu-lar words, which makes it less applicable for text analysis on microblog. In this study, a Simplified Chinese LIWC dictionary is established according to LIWC categories. After translating Traditional Chinese dictionary into Simplified Chi-nese, five thousand words most frequently used in microblog are added into the dictionary. Four graduate students of psychology rated whether each word be-longed in a category. The reliability and validity of Simplified Chinese LIWC dictionary were tested by these four judges. This new dictionary could contri-bute to all the text analysis on microblog in future.
