I am trying to learn Stemming in NLTK and while I try to stem words with SnowballStemmer it has stuck with PorterStemmer.
Although when I try to stem one single word it works properly but when I try to stem a list of words, it stems with PorterStemmer.
I have created a new list named "singles" to add all the stem words into that list but the result is not what I am looking for.
As you can see, when I used "generously", everything looks just fine, but when I try to print "singles" which is supposed to include all the stem words of "plurals" list, I get the stem words with PorterStemmer.
from nltk.stem.snowball import SnowballStemmer
plurals = ['caresses', 'flies', 'dies', 'mules', 'denied','died', 'agreed', 'owned', 'humbled', 'sized','meeting', 'stating', 'siezing', 'itemization','sensational', 'traditional', 'reference', 'colonizer','plotted']
stemmer = SnowballStemmer("english")
singles = [stemmer.stem(plural) for plural in plurals]
print(SnowballStemmer("english").stem("generously"))
print(" ".join(singles))
The issue is that I don't what to stem "generously", I want to stem the list named "plurals". I just added "generously" to show that it works fine for one word but not for a list.
I would really appreciate it if you help me understand what I am missing.
