LIWC
Pennebaker and his colleagues started in early 1990 to develop a computerized tool for language feature analysis. Among all possible approaches, Pennebaker decided to return to the very basic unit in writing, i.e., the use of word. Later on, literature confirmed his approach that the simplest fact provides the most direct evidence. The use of words in the daily language, as indexed by the frequency of occurrence,could effectively reflect important psychological processes. This program along with its dictionary is called the Linguistic Inquiry and Word Count, LIWC). There have been several revisions in the past years including, LIWC (Francis & Pennebaker, 1993), LIWC2001(Pennebaker, Francis, & Booth, 2001), to the most recent LIWC2007 (Pennebaker, Booth, & Francis, 2007; Pennebaker, Chung, Ireland, Gonzales, & Booth, 2007). Hundreds of research have also demonstrated its reliability and validity.
