The English stopwords are taken from the SMART information retrieval system (obtained from Lewis, David D., et al. "Rcv1: A new benchmark collection for text categorization research." Journal of machine learning research (2004, 5 April): 361-397. Additional stopword lists are taken from the Snowball stemmer project in different languages (see The Greek stopwords were supplied by Carsten Schwemmer (see GitHub issue #282).


a character vector of stopwords


The stopword list is an internal data object named data_char_stopwords, which consists of English stopwords from the SMART information retrieval system (obtained from Lewis et. al. (2004) and a set of stopword lists from the Snowball stemmer project in different languages (see See data_char_stopwords for details.
