LIWC
Linguistic Inquiry and Word Count (LIWC - http://www.liwc.net/) is a text analysis software that calculates the degree of use for different categories of words across a wide array of texts [Pennebaker et al. 2001]. The core of this program is a lexicon resource, best known as LIWC dictionary, which recently has been made available for Portuguese Language, named Brazilian Portuguese LIWC 2007 Dictionary .
