JSTOR_removestopwords: Removes stopwords from a corpus

In benmarwick/JSTORr: Simple Text Mining and Document Clustering of JSTOR Journal Articles

Description

This function removes stopwords from a corpus (it is a simple wrapper for tm::removeWords). Note that the function JSTOR_corpusofnouns contains this stopword removal function also, but it can be very slow due to the part-of-speech tagging. As a convenience, the stopword removal function is provided separately to enable quick repeats of the stopword removal process as the stopword list is updated and other functions are re-run. This function uses the stopword list in the tm package. The location of tm's English stopwords list can be found by entering this at the R prompt: paste0(.libPaths()[1], "/tm/stopwords/english.dat")

Usage

JSTOR_removestopwords(corpus)

Arguments

corpus

object returned by the function JSTOR_corpusofnouns or any corpus produced by the tm package.

Value

Returns a corpus containing documents with stopwords removed, ready for more advanced text mining and topic modelling.

Examples

## mycorpus <- JSTOR_removestopwords(corpus)
