lexiconPT was developed to make it easy for analysts and
researchers who want to perform text analysis and mining in Portuguese
texts in R. Its main contribution is that it easily imports cleaned
versions of some famous Portuguese lexicons, such as OpLexicon
and SentiLex. These datasets can be loaded to R using the
data() function:
data("sentiLex_lem_PT02")
data("oplexicon_v2.1")
data("oplexicon_v3.0.rda")Also, you can individually check a word sentiment by using the
function lexiconPT::get_word_sentiment():
get_word_sentiment("temer")The cleaning process can be seen in data-raw/setup.R.
Note that, in order to clean the SentiLex dataset in a tidy way, some
assumptions had to be made (I’m gonna write a blog post about it). On
the other hand, both OpLexicon versions were already cleaned.
To know how both lexicons were developed, please see the help pages of the datasets to check their references.
To install lexiconPT, please run
devtools::install_github("sillasgonzaga/lexiconPT").
