This data sets contain very common lists of words that want to be ignored when
building up a document-term matrix. The stop word lists can be loaded by
calling data(stopwords_en)
, data(stopwords_de)
,
data(stopwords_nl)
, data(stopwords_ar)
, etc. The objects stopwords_de
, stopwords_en
, stopwords_nl
, stopwords_ar
, etc. must already exist before being handed over to textmatrix()
.
The French stopword list has been combined by Haykel Demnati by integrating the lists from rank.nl (www.rank.nl/stopwors/french.html), the one from the CLEF team at the University of Neuchatel (http://members.unine.ch/jacques.savoy/clef/frenchST.txt), and the one prepared by Jean V<U+00E9>ronis (http://sites.univ-provence.fr/veronis/data/antidico.txt).
The Polish stopword list has been contributed by Grazyna Paliwoda-Pekosz, Cracow University of Economics and is taken from the Polish Wikipedia.
The Arab stopword list has been contributed by Marwa Naili, Tunisia. The list is based on the stopword lists by Shereen Khoja and by Siham Boulaknadel.
