我想刪除文件中的停用單詞(它包含一個句子,一個選項卡,然後是一個英文單詞)。停用詞是在一個單獨的文件中,語言是波斯語。下面的代碼工作,但問題是,它會刪除一行中的停用詞,但不會刪除其他行中的同一停用詞。它發生幾乎每一個停止詞。我猜也許它可以用於正常化。所以我通過導入hazm模塊(hazm就像NLTK,波斯語)來標準化這兩個文件。但問題沒有改變。一些身體可以幫助嗎?刪除文件中的特定單詞
from hazm import*
punctuation = '!"#$%&\'()*+,-./:;<=>[email protected][\\]^_`{|}~،؟«؛'
file1 = "stopwords.txt"
file2 = "test/پر.txt"
witoutStops = []
corpuslines = []
def RemStopWords (file1, file2):
with open(file1, encoding = "utf-8") as stopfile:
normalizer = Normalizer()
stopwords = stopfile.read()
stopwords = normalizer.normalize(stopwords)
with open(file2, encoding = "utf-8") as trainfile:
with open ("y.txt", "w", encoding = "utf-8") as newfile:
for line in trainfile:
tmp = line.strip().split("\t")
tmp[0] = normalizer.normalize(tmp[0])
corpuslines.append(tmp)
for row in corpuslines:
line = ""
tokens = row[0].split()
for token in tokens:
if token not in stopwords:
line += token + " "
line = line.strip() + "\n"
for i in punctuation: # deletes punctuations
if i in line:
line = line.replace(i, "")
newfile.write(line)
witoutStops.append (line)
