Answer 1

使用 NLTK 库 提供的停用词：

stopwords = ['i','me','my','myself','we','our','ours','ourselves','you','your','yours','yourself','yourselves','he','him','his','himself','she','her','hers','herself','it','its','itself','they','them','their','theirs','themselves','what','which','who','whom','this','that','these','those','am','is','are','was','were','be','been','being','have','has','had','having','do','does','did','doing','a','an','the','and','but','if','or','because','as','until','while','of','at','by','for','with','about','against','between','into','through','during','before','after','above','below','to','from','up','down','in','out','on','off','over','under','again','further','then','once','here','there','when','where','why','how','all','any','both','each','few','more','most','other','some','such','no','nor','not','only','own','same','so','than','too','very','s','t','can','will','just','don','should','now']

然后只需将您的字符串传递到以下函数中：

function remove_stopwords(str) {
    res = []
    words = str.split(' ')
    for(i=0;i<words.length;i++) {
       word_clean = words[i].split(".").join("")
       if(!stopwords.includes(word_clean)) {
           res.push(word_clean)
       }
    }
    return(res.join(' '))
}  

示例：

remove_stopwords("I will go to the place where there are things for me.")

结果：

I go place things

只需将尚未涵盖的任何单词添加到 NLTK 数组中即可。

Answer 2

我认为没有此类库，您需要从 https://www.ranks.nl 下载这些单词/停用词。

然后将单词替换如下：

text = text.replace(stopword, "")

Answer 3

这是一个包含英语停用词的数组。希望有帮助。来自 http://www.ranks.nl/stopwords （在前面的答案中提到）。
