Recently I've been doing some text mining and the stemming processing is taking a lot of time (I'm working with portuguese language).
I found the
hunspell package, that provides spell checking, corrections and stemming.
Also, a friend developed another stemming function that I've been studying (RSLP: Removedor de Sufixos da Língua Portuguesa).
But both were made to work on a char vector, and I need to make them work with the
tm_map function that read a corpus.
I know that to make them work, I need to split the documents on the corpus into single words, but I don't know how.
